–4-Amino-3-hydroxynaphthalene-1-sulfonic acid diazo, and Naphthalen-2-ol coupling, and then translate into 1:2 chromium complex.Check Digit Verification of cas no
The CAS Registry Mumber 12238-87-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,2,2,3 and 8 respectively; the second part has 2 digits, 8 and 7 respectively.Calculate Digit Verification of CAS Registry Number 12238-87:
(7*1)+(6*2)+(5*2)+(4*3)+(3*8)+(2*8)+(1*7)=88
88 % 10 = 8
So 12238-87-8 is a valid CAS Registry Number.
