Check Digit Verification of cas no

The CAS Registry Mumber 152786-08-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,2,7,8 and 6 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 152786-08:
(8*1)+(7*5)+(6*2)+(5*7)+(4*8)+(3*6)+(2*0)+(1*8)=148
148 % 10 = 8
So 152786-08-8 is a valid CAS Registry Number.

METHOD FOR SYNTHESIZING SAPROPTERIN DIHYDROCHLORIDE

-

, (2015/03/03)

Disclosed is a method for synthesizing sapropterin dihydrochloride. The present invention reduces a synthesis route of the sapropterin dihydrochloride, and resolves a racemate intermediate or an intermediate having a low antimer isomerism value by using a chiral resolving reagent, thereby obtaining an intermediate having a high antimer isomerism value. Raw materials are cheap and readily available, and the cost is significantly reduced, hence providing an effective scheme for mass industrial production of the sapropterin dihydrochloride.

Paragraph 0053, (2015/04/22)

Disclosed is a method for synthesizing sapropterin dihydrochloride. The present disclosure reduces a synthesis route of the sapropterin dihydrochloride, introduces a chiral center in an asymmetric synthesis manner, in which a tetrahydrofuran solution containing a samarium catalyst is adopted as a catalyst, and obtains a target compound having a high antimer isomerism value by means of selective catalysis. The yield is improved, raw materials are cheap and readily available, and the cost is significantly reduced, hence providing an effective scheme for mass industrial production of the sapropterin dihydrochloride.

Total synthesis of (-)-Jiadifenin

Yang, Yang,Fu, Xingnian,Chen, Jianwei,Zhai, Hongbin

supporting information, p. 9825 - 9828 (2012/10/29)

As easy as ABCD: (-)-Jiadifenin was synthesized in eighteen reaction steps from 1-[(E)-(4′-bromo-2′-butenyl)oxy]-4-methoxybenzene. Key features of this synthesis include: 1) Ireland-Claisen rearrangement to produce the two contiguous quaternary centers at

Scalable synthesis of enantiomerically pure syn -2,3-dihydroxybutyrate by sharpless asymmetric dihydroxylation of p -phenylbenzyl crotonate

Smaltz, Daniel J.,Myers, Andrew G.

experimental part, p. 8554 - 8559 (2011/12/03)

An efficient four-step synthetic route to the useful chiral building block (2R,3S)-dihydroxybutyric acid acetonide in >95% ee is detailed. The sequence is readily scaled, requires no chromatography, and allows for efficient recycling of p-phenylbenzyl alcohol, an expedient for enantio- and diastereoenrichment by recrystallization.
