Check Digit Verification of cas no
The CAS Registry Mumber 231934-87-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,3,1,9,3 and 4 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 231934-87:
(8*2)+(7*3)+(6*1)+(5*9)+(4*3)+(3*4)+(2*8)+(1*7)=135
135 % 10 = 5
