Check Digit Verification of cas no

The CAS Registry Mumber 853783-20-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,5,3,7,8 and 3 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 853783-20:
(8*8)+(7*5)+(6*3)+(5*7)+(4*8)+(3*3)+(2*2)+(1*0)=197
197 % 10 = 7
So 853783-20-7 is a valid CAS Registry Number.

The Total Synthesis of Spermine Alkaloid Kukoamine Bimesylate

Dong, Kai

, p. 2669 - 2672 (2018/12/14)

The first total synthesis of kukoamine B bimesylate was completed from 1,4-diaminobutane dihydrochloride in 12 steps with a 11.4% overall yield, and all the steps could be carried out at a kilogram scale. The cyano groups were used as the precursor of amino groups to avoid the competitive reaction delicately. The aza-Michael addition reaction, amidation and hydrogenation of the cyano group sequence was streamlined as a general approach towards the synthesis of polyamine structures.

Efficient synthesis of orthogonally protected spermidine and norspermidine derivatives

Andruszkiewicz, Ryszard,Radowski, Michal,Czajgucki, Zbigniew

, p. 1085 - 1094 (2007/10/03)

Several orthogonally protected spermidine and norspermidine derivatives have been synthesized via cyanoethylation of monoprotected 1,4-butanediamine (putrescine) or 1,3-propanediamine followed by protection of their secondary amino groups and final reduct
