Check Digit Verification of cas no
The CAS Registry Mumber 1111797-16-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,1,1,7,9 and 7 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1111797-16:
(9*1)+(8*1)+(7*1)+(6*1)+(5*7)+(4*9)+(3*7)+(2*1)+(1*6)=130
130 % 10 = 0
So 1111797-16-0 is a valid CAS Registry Number.
