6251-36-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 6251-36-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,2,5 and 1 respectively; the second part has 2 digits, 3 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 6251-36:
(6*6)+(5*2)+(4*5)+(3*1)+(2*3)+(1*6)=81
81 % 10 = 1
So 6251-36-1 is a valid CAS Registry Number.
