Check Digit Verification of cas no

The CAS Registry Mumber 76994-91-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,6,9,9 and 4 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 76994-91:
(7*7)+(6*6)+(5*9)+(4*9)+(3*4)+(2*9)+(1*1)=197
197 % 10 = 7
So 76994-91-7 is a valid CAS Registry Number.

Synthesis and Reduction of Carbohydrate Benzylidene Hemithioacetal Diastereomers with LiAlH4-AlCl3

Fuegedi, Peter,Liptak, Andras

, p. 1234 - 1235 (1980)

Reduction of methyl 2-O-benzyl-endo- (11) and -exo-3-O-4-S-benzylidene-4,6-dideoxy-4-thio-α-D-galactopyranoside (12) gives the same S-benzyl derivative (6), but with very different reaction rates, indicating that the configuration of the acetal carbon con
