The CAS Registry Mumber 632-68-8 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 6,3 and 2 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 632-68:
(5*6)+(4*3)+(3*2)+(2*6)+(1*8)=68
68 % 10 = 8
So 632-68-8 is a valid CAS Registry Number.
