7404-34-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 7404-34-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,4,0 and 4 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 7404-34:
(6*7)+(5*4)+(4*0)+(3*4)+(2*3)+(1*4)=84
84 % 10 = 4
So 7404-34-4 is a valid CAS Registry Number.

A novel protocol for the regioselective bromination of primary alcohols in unprotected carbohydrates or glycosides
Xue, Weihua,Zhang, Lifen
experimental part, p. 1429 - 1432 (2012/09/07)
The regioselective and efficient bromination of primary hydroxyl groups in unprotected carbohydrates or glycosides is successfully achieved by using (chloro-phenylthio-methylene)dimethylammoniumchloride (CPMA) in the presence of tetrabutylammonium bromide
