Check Digit Verification of cas no
The CAS Registry Mumber 1028-91-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,0,2 and 8 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1028-91:
(6*1)+(5*0)+(4*2)+(3*8)+(2*9)+(1*1)=57
57 % 10 = 7
So 1028-91-7 is a valid CAS Registry Number.

ACTION OF NITROUS ACID ON N-SUBSTITUTED-ISATINIC ACIDS. DISPROPORTIONATION TO INDAZOLOLS.
Baiocchi,Leandro,Picconi, Giuseppe
, p. 3651 - 3652 (2007/10/02)
By reacting N-substituted-2-isatinic acids with nitrous acid, indazolols, N-nitroso-N-substituted anthranilic acids and the esters of said acids with the above mentioned indazolols were obtained through disproportionation of the N-nitroso-N-substituted-isatinic acids.
