Check Digit Verification of cas no
The CAS Registry Mumber 182699-39-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,2,6,9 and 9 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 182699-39:
(8*1)+(7*8)+(6*2)+(5*6)+(4*9)+(3*9)+(2*3)+(1*9)=184
184 % 10 = 4
So 182699-39-4 is a valid CAS Registry Number.

-
, (2008/06/13)
A process for preparing an optically active (2S,3S)-allophenylnorstatin derivative (I) is disclosed, comprising asymmetrically hydrogenating a 4-phenyl-2-halogeno-3-oxobutyric ester (III) in the presence of a ruthenium-phosphine complex to obtain a 4-phen
