Check Digit Verification of cas no

The CAS Registry Mumber 176656-93-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,6,6,5 and 6 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 176656-93:
(8*1)+(7*7)+(6*6)+(5*6)+(4*5)+(3*6)+(2*9)+(1*3)=182
182 % 10 = 2
So 176656-93-2 is a valid CAS Registry Number.

An efficient synthesis of cis-3-hydroxy-4-phenyl-β-lactams: Precursor for taxol side chain

Srirajan,Deshmukh,Bhawal

, p. 5585 - 5590 (1996)

Chiral ketone precursors derived from naturally occurring (+)-3-carene have been used for the synthesis of β-lactams via the Staudinger reaction. The major diastereomer 5a was separated by crystallization and converted in very good yield into (3R,4S)-3-hy
