Check Digit Verification of cas no
The CAS Registry Mumber 88-52-8 includes 5 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 2 digits, 8 and 8 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 88-52:
(4*8)+(3*8)+(2*5)+(1*2)=68
68 % 10 = 8
So 88-52-8 is a valid CAS Registry Number.
