33631-41-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 33631-41-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,3,6,3 and 1 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 33631-41:
(7*3)+(6*3)+(5*6)+(4*3)+(3*1)+(2*4)+(1*1)=93
93 % 10 = 3
So 33631-41-3 is a valid CAS Registry Number.

Synthesis and properties of some 13-cis- and all-trans-retinamides
Shealy,Frye,O'Dell,Thorpe,Kirk,Coburn Jr.,Sporn
, p. 745 - 751 (2007/10/02)
Several 13-cis-retinamides were synthesized from 13-cis-retinoic acid via either 13-cis-retinoyl chloride or 13-cis-1-retinoylimidazole. All-trans-retinoylglycine was prepared from all-trans-retinoyl chloride and ethyl glycinate. Detailed procedures were developed for the preparation of other all-trans-retinamides on a large scale for studies of the chemoprevention of cancer.
