139936-63-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 139936-63-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,9,9,3 and 6 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 139936-63:
(8*1)+(7*3)+(6*9)+(5*9)+(4*3)+(3*6)+(2*6)+(1*3)=173
173 % 10 = 3
So 139936-63-3 is a valid CAS Registry Number.
