Check Digit Verification of cas no
The CAS Registry Mumber 116516-01-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,6,5,1 and 6 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 116516-01:
(8*1)+(7*1)+(6*6)+(5*5)+(4*1)+(3*6)+(2*0)+(1*1)=99
99 % 10 = 9
So 116516-01-9 is a valid CAS Registry Number.
