139213-33-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 139213-33-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,9,2,1 and 3 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 139213-33:
(8*1)+(7*3)+(6*9)+(5*2)+(4*1)+(3*3)+(2*3)+(1*3)=115
115 % 10 = 5
So 139213-33-5 is a valid CAS Registry Number.
