Check Digit Verification of cas no

The CAS Registry Mumber 1158998-90-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,5,8,9,9 and 8 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1158998-90:
(9*1)+(8*1)+(7*5)+(6*8)+(5*9)+(4*9)+(3*8)+(2*9)+(1*0)=223
223 % 10 = 3
So 1158998-90-3 is a valid CAS Registry Number.

Poly(N,N′-dichloro-N-ethylbenzene-1,3-disulfonamide) and N,N,N′,N′-tetrachlorobenzene-1,3-disulfonamide as novel reagents for the synthesis of N-chloroamines, nitriles and aldehydes

Ghorbani-Vaghei, Ramin,Veisi, Hojat

, p. 945 - 950 (2009)

The applications of poly(N,N′-dichloro-N-ethylbenzene-1,3- disulfonamide) (PCBS) and N,N,N′,N′-tetrachlorobenzene-1,3- disulfonamide (TCBDA) as novel reagents for the preparation of N,N-dichloroamines, nitriles, and aldehydes from primary amines under various conditions are described. Also, a simple and effective procedure for the direct oxidative conversion of primary alcohols into nitriles was successfully carried out with TCBDA and PCBS in aqueous ammonia.
