Check Digit Verification of cas no

The CAS Registry Mumber 4239-73-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,2,3 and 9 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 4239-73:
(6*4)+(5*2)+(4*3)+(3*9)+(2*7)+(1*3)=90
90 % 10 = 0
So 4239-73-0 is a valid CAS Registry Number.

The Reaction of N-Dichloromethylene-N,N-dimethylammonium chloride (Viehe's Salt) with 1,2:5,6-Di-O-isopropylidene-α-D-glucose

Copeland, Christopher,Stick, Robert V.

, p. 2269 - 2275 (2007/10/02)

The treatment of 1,2:5,6-di-O-isopropylidene-α-D-glucose with N-dichloromethylene-N,N-dimethylammonium chloride (Viehe's salt) (2:1 or 1:1) gives two iminium salts.These are readily hydrolysed to a carbonate and a carbamate.Treatment with sodium hydrogen
