The CAS Registry Mumber 60800-55-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,0,8,0 and 0 respectively; the second part has 2 digits, 5 and 5 respectively.Calculate Digit Verification of CAS Registry Number 60800-55:
(7*6)+(6*0)+(5*8)+(4*0)+(3*0)+(2*5)+(1*5)=97
97 % 10 = 7
So 60800-55-7 is a valid CAS Registry Number.
