901-71-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 901-71-3 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 9,0 and 1 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 901-71:
(5*9)+(4*0)+(3*1)+(2*7)+(1*1)=63
63 % 10 = 3
So 901-71-3 is a valid CAS Registry Number.
