Check Digit Verification of cas no
The CAS Registry Mumber 126832-13-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,6,8,3 and 2 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 126832-13:
(8*1)+(7*2)+(6*6)+(5*8)+(4*3)+(3*2)+(2*1)+(1*3)=121
121 % 10 = 1
So 126832-13-1 is a valid CAS Registry Number.
