Check Digit Verification of cas no

The CAS Registry Mumber 133217-39-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,3,2,1 and 7 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 133217-39:
(8*1)+(7*3)+(6*3)+(5*2)+(4*1)+(3*7)+(2*3)+(1*9)=97
97 % 10 = 7
So 133217-39-7 is a valid CAS Registry Number.

Acyloxymethyl carbonochloridates. New intermediates in prodrug synthesis

Folkmann,Lund

, p. 1159 - 1166 (2007/10/02)

The synthesis of a number of stable acyloxymethyl carbonochloridates 7 has been accomplished in four steps from chloromethyl carbonochloridate 3. Each step has been optimized with propanoyl-oxymethyl carbonochloridate 7c as a model compound (64% overall yield). Diethyl ether-boron trifluoride catalyzes the conversion of carbonothioate 6cc to the carbonochloridate 7c by chlorination with sulfuryl chloride. Acylation of a few compounds containing hydroxy or amino groups by 7c is described.
