Check Digit Verification of cas no
The CAS Registry Mumber 16013-84-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,6,0,1 and 3 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 16013-84:
(7*1)+(6*6)+(5*0)+(4*1)+(3*3)+(2*8)+(1*4)=76
76 % 10 = 6
So 16013-84-6 is a valid CAS Registry Number.
