Check Digit Verification of cas no
The CAS Registry Mumber 135967-13-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,5,9,6 and 7 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 135967-13:
(8*1)+(7*3)+(6*5)+(5*9)+(4*6)+(3*7)+(2*1)+(1*3)=154
154 % 10 = 4
So 135967-13-4 is a valid CAS Registry Number.
