The CAS Registry Mumber 29-68-5 includes 5 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 2 digits, 2 and 9 respectively; the second part has 2 digits, 6 and 8 respectively.Calculate Digit Verification of CAS Registry Number 29-68:
(4*2)+(3*9)+(2*6)+(1*8)=55
55 % 10 = 5
So 29-68-5 is a valid CAS Registry Number.
