98039-21-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 98039-21-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,8,0,3 and 9 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 98039-21:
(7*9)+(6*8)+(5*0)+(4*3)+(3*9)+(2*2)+(1*1)=155
155 % 10 = 5
So 98039-21-5 is a valid CAS Registry Number.

Studies on the synthesis of myriaporones: Stereoselective synthesis of the C5-C13 fragment starting from D-glucose via regioselective reductive opening of methoxybenzylidene acetal

Zheng,Yamauchi,Dei,Yonemitsu

, p. 1761 - 1765 (2007/10/03)

A stereoselective synthesis is described of the C5-C13 fragment (4) of myriaporone 4 (1) starting from D-glucose by a coupling of the C5-C9 aldehyde (5), prepared using a regioselective reductive ring-opening of methoxybenzylidene acetal, with the C10-C13 iodoolefin (6).

Chiral Synthesis of Polyketide-derived Natural Products. Part 5. Synthesis of a Chiral Segment Corresponding to the C-1-C-5 Unit of Erythromycin A from D-Glucose

Oikawa, Yuji,Nishi,Takao,Yonemitsu, Osamu

, p. 19 - 26 (2007/10/02)

As a right-hand segment with three consecutive chiral centres corresponding to the C-1-C-5 unit of erythromycin A (1), (2S,3R,4S)-3,5-isopropylidenedioxy-2,4-dimethylpentanal (32) was synthesized from D-glucose (5) by application of MPM (4-methoxybenzyl)
