Check Digit Verification of cas no
The CAS Registry Mumber 68037-87-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,8,0,3 and 7 respectively; the second part has 2 digits, 8 and 7 respectively.Calculate Digit Verification of CAS Registry Number 68037-87:
(7*6)+(6*8)+(5*0)+(4*3)+(3*7)+(2*8)+(1*7)=146
146 % 10 = 6
So 68037-87-6 is a valid CAS Registry Number.
