Check Digit Verification of cas no
The CAS Registry Mumber 64173-96-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,4,1,7 and 3 respectively; the second part has 2 digits, 9 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 64173-96:
(7*6)+(6*4)+(5*1)+(4*7)+(3*3)+(2*9)+(1*6)=132
132 % 10 = 2
So 64173-96-2 is a valid CAS Registry Number.

Sulfochlorination of 1,2-Naphthoquinone-(2)-diazide by Chlorosulfonic acid
Sauer, E.,Polz, K.,Schopf, G.,Bendig, J.
, p. 467 - 473 (2007/10/02)
The sulfochlorination of 1,2-naphthoquinone diazide-(2) (1) by chlorosulfonic acid was investigated.The yields of the formed products (1,2-naphthoquinone diazide-(2)-4-sulfonic acid (4), 1,2-naphthoquinone diazide-(2)-5-sulfonic acid (5), 1,2-naphthoquinone diazide-(2)-4-sulfochloride (2) and 1,2-naphthoquinone diazide-(2)-5-sulfochloride (3)) depend on the temperature and on the time of reaction.The highest yields of the favoured 1,2-naphthoquinone diazide-(2)-4-sulfochloride (2) are obtained at 63 deg C and after a reaction time of 80 minutes (50percent).
