Check Digit Verification of cas no
The CAS Registry Mumber 842-19-3 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 8,4 and 2 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 842-19:
(5*8)+(4*4)+(3*2)+(2*1)+(1*9)=73
73 % 10 = 3
So 842-19-3 is a valid CAS Registry Number.
