Check Digit Verification of cas no
The CAS Registry Mumber 878194-91-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,7,8,1,9 and 4 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 878194-91:
(8*8)+(7*7)+(6*8)+(5*1)+(4*9)+(3*4)+(2*9)+(1*1)=233
233 % 10 = 3
So 878194-91-3 is a valid CAS Registry Number.
