Check Digit Verification of cas no
The CAS Registry Mumber 68131-77-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,8,1,3 and 1 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 68131-77:
(7*6)+(6*8)+(5*1)+(4*3)+(3*1)+(2*7)+(1*7)=131
131 % 10 = 1
So 68131-77-1 is a valid CAS Registry Number.
