Check Digit Verification of cas no

The CAS Registry Mumber 90762-39-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,0,7,6 and 2 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 90762-39:
(7*9)+(6*0)+(5*7)+(4*6)+(3*2)+(2*3)+(1*9)=143
143 % 10 = 3
So 90762-39-3 is a valid CAS Registry Number.

A practical conversion of an azetidinone to penem: Synthesis of Sch 34343

Gala,Chiu,Ganguly,Girijavallabhan,Jaret,Jenkins,McCombie,Nyce,Rosenhouse,Steinman

, p. 1175 - 1182 (2007/10/02)

A synthesis of penems from azetidinone 1 is described in detail. This synthesis is used to prepare multikilo batches of (5R,6S)-2-[[-(carbamoyloxy)ethyl]thio]-6-[(R)-1-hydroxyethyl]penem-3-carboxylic acid (10), (Sch 34343). It is practical as all chemical
