Check Digit Verification of cas no
The CAS Registry Mumber 7379-35-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,3,7 and 9 respectively; the second part has 2 digits, 3 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 7379-35:
(6*7)+(5*3)+(4*7)+(3*9)+(2*3)+(1*5)=123
123 % 10 = 3
So 7379-35-3 is a valid CAS Registry Number.

The chlorination of hydroxy aza-arenes with bis(trichloromethyl) carbonate (BTC) and SOCl2 has been effectively performed by refluxing with 5 wt % 4-dimethylaminopyridine (DMAP) as a catalyst. Various substrates are chlorinated with high yields. The obtained chlorinated aza-arenes can be used directly with simple workup for succedent one-pot synthesis on a large scale.
