Check Digit Verification of cas no

The CAS Registry Mumber 221878-99-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,1,8,7 and 8 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 221878-99:
(8*2)+(7*2)+(6*1)+(5*8)+(4*7)+(3*8)+(2*9)+(1*9)=155
155 % 10 = 5
So 221878-99-5 is a valid CAS Registry Number.

Highly efficient double enantioselection by lipase-catalyzed transesterification of (R,S)-carboxylic acid vinyl esters with (RS)-1- phenylethanol

Yang, Hong,Henke, Erik,Bornscheuer, Uwe T.

, p. 957 - 960 (2007/10/03)

Transesterification of the title compounds using lipase B from Candida antarctica in toluene afforded the corresponding esters in good to excellent diastereomeric excess. (R)-2-Phenylpropionic acid-(R)-1-phenethyl ester 4 was isolated in 45% yield and 64%
