Check Digit Verification of cas no
The CAS Registry Mumber 136814-87-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,6,8,1 and 4 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 136814-87:
(8*1)+(7*3)+(6*6)+(5*8)+(4*1)+(3*4)+(2*8)+(1*7)=144
144 % 10 = 4
So 136814-87-4 is a valid CAS Registry Number.
