Check Digit Verification of cas no

The CAS Registry Mumber 52844-49-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,2,8,4 and 4 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 52844-49:
(7*5)+(6*2)+(5*8)+(4*4)+(3*4)+(2*4)+(1*9)=132
132 % 10 = 2
So 52844-49-2 is a valid CAS Registry Number.

INTERCONVERSION OF THE THIAZINE AND THIAZOLIDINE SYSTEM OF β-LACTAM ANTIBIOTICS. ELECTROCHEMICAL CLEAVAGE OF KAMIYA'S DISULPHIDE PROMOTED BY BROMIDE ION

Balsamo, Aldo,Benedini, Paola Maria,Giorgi, Irene,Macchia, Bruno,Macchia, Franco

, p. 2991 - 2994 (1982)

A new transformation of Kamiya's disulphide (1) into the bromopenam derivative (4) has been carried out by eletrolyzing the disulphide (1) in protic solvents in the presence of Me4NBr.The transformation occurs through an intermediate episulphonium-bromide ion pair in which the bromide appears to be tightly linked to the sulphur.
