153813-83-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 153813-83-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,3,8,1 and 3 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 153813-83:
(8*1)+(7*5)+(6*3)+(5*8)+(4*1)+(3*3)+(2*8)+(1*3)=133
133 % 10 = 3
So 153813-83-3 is a valid CAS Registry Number.
