33980-83-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 33980-83-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,3,9,8 and 0 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 33980-83:
(7*3)+(6*3)+(5*9)+(4*8)+(3*0)+(2*8)+(1*3)=135
135 % 10 = 5
So 33980-83-5 is a valid CAS Registry Number.
