Check Digit Verification of cas no
The CAS Registry Mumber 8031-18-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 8,0,3 and 1 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 8031-18:
(6*8)+(5*0)+(4*3)+(3*1)+(2*1)+(1*8)=73
73 % 10 = 3
So 8031-18-3 is a valid CAS Registry Number.
