Check Digit Verification of cas no
The CAS Registry Mumber 80631-44-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,0,6,3 and 1 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 80631-44:
(7*8)+(6*0)+(5*6)+(4*3)+(3*1)+(2*4)+(1*4)=113
113 % 10 = 3
So 80631-44-3 is a valid CAS Registry Number.
