Check Digit Verification of cas no

The CAS Registry Mumber 89753-73-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,9,7,5 and 3 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 89753-73:
(7*8)+(6*9)+(5*7)+(4*5)+(3*3)+(2*7)+(1*3)=191
191 % 10 = 1
So 89753-73-1 is a valid CAS Registry Number.

SYNTHESIS OF 2-(HETEROCYCLYLTHIOMETHYL)PENEMS

Alpegiani, Marco,Bedeschi, Angelo,Franceschi, Giovanni,Giudici, Franco,Nannini, Giuliano,Perrone, Ettore

, p. 319 - 324 (2007/10/02)

The synthesis of representatives of an important class of penem antibiotics is described, exploiting a new procedure for preparing phosphoranes from base-sensitive chlorides and a purpose-tailored carboxyl protective group.Double bond migration out of the ring to give 2-(heterocyclylthiomethylene)penams was observed even in pH 7.4 phosphate buffer.
