Check Digit Verification of cas no
The CAS Registry Mumber 16021-25-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,6,0,2 and 1 respectively; the second part has 2 digits, 2 and 5 respectively.Calculate Digit Verification of CAS Registry Number 16021-25:
(7*1)+(6*6)+(5*0)+(4*2)+(3*1)+(2*2)+(1*5)=63
63 % 10 = 3
So 16021-25-3 is a valid CAS Registry Number.
