Check Digit Verification of cas no
The CAS Registry Mumber 90640-02-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,0,6,4 and 0 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 90640-02:
(7*9)+(6*0)+(5*6)+(4*4)+(3*0)+(2*0)+(1*2)=111
111 % 10 = 1
So 90640-02-1 is a valid CAS Registry Number.

Mosandl, Armin
, p. 345 - 352 (2007/10/02)
The synthesis of 3-methyl-3-phenyl-N-glycidamide results in four stereoisomers.The pair of Z-diastereomers was separated by liquid chromatography and the configurations of the corresponding enantiomeric glycidic acids were determined by
