Check Digit Verification of cas no
The CAS Registry Mumber 83012-12-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,3,0,1 and 2 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 83012-12:
(7*8)+(6*3)+(5*0)+(4*1)+(3*2)+(2*1)+(1*2)=88
88 % 10 = 8
So 83012-12-8 is a valid CAS Registry Number.
