831-55-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 831-55-0 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 8,3 and 1 respectively; the second part has 2 digits, 5 and 5 respectively.Calculate Digit Verification of CAS Registry Number 831-55:
(5*8)+(4*3)+(3*1)+(2*5)+(1*5)=70
70 % 10 = 0
So 831-55-0 is a valid CAS Registry Number.
