83831-80-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 83831-80-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,3,8,3 and 1 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 83831-80:
(7*8)+(6*3)+(5*8)+(4*3)+(3*1)+(2*8)+(1*0)=145
145 % 10 = 5
So 83831-80-5 is a valid CAS Registry Number.
