Check Digit Verification of cas no

The CAS Registry Mumber 1353389-29-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,5,3,3,8 and 9 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1353389-29:
(9*1)+(8*3)+(7*5)+(6*3)+(5*3)+(4*8)+(3*9)+(2*2)+(1*9)=173
173 % 10 = 3
So 1353389-29-3 is a valid CAS Registry Number.

Synthetic studies of stereocalpin A and its C5-epimer: Total synthesis of 11-epi- and 5,11-diepi-stereocalpin A

Reddy, K. Mahender,Shashidhar,Pottireddygari, Gurava Reddy,Ghosh, Subhash

, p. 5987 - 5991 (2011/11/29)

This Letter describes the synthetic studies of stereocalpin A and its C5-epimer. After various cyclization attempts, successful macrolactamization at 9-10 position was tried inorder to obtain stereocalpin A and its C5-epimer, which were accompanied by complete racemization and resulted in the synthesis of 11-epi- and 5,11-diepi-stereocalpin A. Highly functionalized octanoic acid motif of the depsipeptide was constructed by applying Paterson's aldol methodology, owing to its diversity in synthesizing various analogs of aliphatic acid.
