Check Digit Verification of cas no

The CAS Registry Mumber 94764-21-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,4,7,6 and 4 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 94764-21:
(7*9)+(6*4)+(5*7)+(4*6)+(3*4)+(2*2)+(1*1)=163
163 % 10 = 3
So 94764-21-3 is a valid CAS Registry Number.

An improved, general procedure to S-aryl thiol esters: A new synthetic application of dry arenediazonium o-benzenedisulfonimides

Barbero, Margherita,Degani, Iacopo,Dughera, Stefano,Fochi, Rita

, p. 1225 - 1230 (2007/10/03)

The reaction between dry arenediazonium o-benzenedisulfonimides (1) and sodium thioacetate or thiobenzoate in anhydrous acetonitrile at room temperature is an efficient and safe procedure, of general validity, for the preparation of S-aryl thiol esters. The products can be easily purified and the yields are always very high. Of the 28 considered examples, the average yield of the S-aryl thioacetates (7) was 86% and that of the S-aryl thiobenzoates (8) 88%. It was possible to recover, in good amount and from all the reactions, o-benzenedisulfonimide (9), reusable for the preparation of salts 1.
