Check Digit Verification of cas no
The CAS Registry Mumber 68952-00-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,8,9,5 and 2 respectively; the second part has 2 digits, 0 and 0 respectively.Calculate Digit Verification of CAS Registry Number 68952-00:
(7*6)+(6*8)+(5*9)+(4*5)+(3*2)+(2*0)+(1*0)=161
161 % 10 = 1
So 68952-00-1 is a valid CAS Registry Number.
