136591-63-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 136591-63-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,6,5,9 and 1 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 136591-63:
(8*1)+(7*3)+(6*6)+(5*5)+(4*9)+(3*1)+(2*6)+(1*3)=144
144 % 10 = 4
So 136591-63-4 is a valid CAS Registry Number.
