Check Digit Verification of cas no
The CAS Registry Mumber 8016-38-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 8,0,1 and 6 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 8016-38:
(6*8)+(5*0)+(4*1)+(3*6)+(2*3)+(1*8)=84
84 % 10 = 4
So 8016-38-4 is a valid CAS Registry Number.
