Check Digit Verification of cas no

The CAS Registry Mumber 108792-04-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,8,7,9 and 2 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 108792-04:
(8*1)+(7*0)+(6*8)+(5*7)+(4*9)+(3*2)+(2*0)+(1*4)=137
137 % 10 = 7
So 108792-04-7 is a valid CAS Registry Number.

QUINONE-IMIDES : REGIOSPECIFICITY OF NUCLEOPHILIC ATTACK ON N-ALKANESULPHONYL-N'-ALKANOYL 1,4-BENZOQUINONE-IMINES.

Rajappa, Srinivasaschari,Shenoy, Sharada J.

, p. 5739 - 5746 (2007/10/02)

Substrates such as (2) undergo regiospecific attack by azide and thiocyanate ions at the terminus of the C=C-C=N-CO system.In the case of addition of azide, this is proved by the detailed analysis of the 1H and 13C NMR spectra of the products (11) derived from the quinone-imides (8).The structure of the products obtained by the addition of thiocyanate to the quinone-imides (10) and (20) is proved by their facile cyclisation to the 2-aminobenzothiazoles (18) and (21) respectively.
