Check Digit Verification of cas no

The CAS Registry Mumber 1220-11-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,2,2 and 0 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1220-11:
(6*1)+(5*2)+(4*2)+(3*0)+(2*1)+(1*1)=27
27 % 10 = 7
So 1220-11-7 is a valid CAS Registry Number.

Quinone Imine Route to Benzimidazol-2-ylcarbamates. Part 3. Effect of Extension of Conjugation in the Quinone Imine.

Divakar, Kikkeri J.,Gaikwad Balkrishna V.,Tampal, Nilufer F.,Rajappa, Srinivasachari

, p. 1687 - 1697 (2007/10/02)

5-Aminobenzimidazol-2-ylcarbamates (11) and (17), in which the amine is linked to position 3 of 1,2-benzisothiazole 1,1-dioxide have been synthesised in good yields from the guanidines (10) and (16) by oxidative cyclisation.The cyclisation is regiospecific.It is likely that quinone imines with extended conjugation are intermediates in this reaction.
