Check Digit Verification of cas no

The CAS Registry Mumber 1215080-81-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,1,5,0,8 and 0 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1215080-81:
(9*1)+(8*2)+(7*1)+(6*5)+(5*0)+(4*8)+(3*0)+(2*8)+(1*1)=111
111 % 10 = 1
So 1215080-81-1 is a valid CAS Registry Number.

A facile synthesis of (S)-felodipine

Kwon, Kuktae,Shin, Jung A.,Lee, Hee-Yoon

experimental part, p. 10222 - 10228 (2012/01/05)

A short and facile synthesis of (S)-felodipine was developed starting from (R)-glycidol as the source of the chiral auxiliary. 2-Hydroxyethyl esters were found to undergo selective transesterification reactions in the presence of other esters. This selective transesterification reaction was applied to the synthesis of (S)-felodipine through selective substitution of the 2-hydroxyethyl group possessing chiral ester with sodium methoxide.
