Check Digit Verification of cas no
The CAS Registry Mumber 86-19-1 includes 5 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 2 digits, 8 and 6 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 86-19:
(4*8)+(3*6)+(2*1)+(1*9)=61
61 % 10 = 1
So 86-19-1 is a valid CAS Registry Number.
