Check Digit Verification of cas no

The CAS Registry Mumber 76368-25-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,6,3,6 and 8 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 76368-25:
(7*7)+(6*6)+(5*3)+(4*6)+(3*8)+(2*2)+(1*5)=157
157 % 10 = 7
So 76368-25-7 is a valid CAS Registry Number.

ASYMMETRIC SYNTHESIS OF β-LACTAMS. II. HIGHLY EFFECTIVE ASYMMETRIC INDUCTION BY MEANS OF "TITANIUM TEMPLATE"

Ojima, Iwao,Inaba, Shin-ichi

, p. 2081 - 2084 (1980)

The reaction of dimethylketene methyl trimethylsilyl acetal with the Schiff bases of chiral α-amino esters in the presence of titanium tetrachloride gave the corresponding β-lactams with extremely high stereoselectivity (up to 99percent diastereomeric purity).Possible mechanism for the highly effective assymmetric induction using "titanium template" is proposed.
