Check Digit Verification of cas no
The CAS Registry Mumber 1169620-16-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,6,9,6,2 and 0 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1169620-16:
(9*1)+(8*1)+(7*6)+(6*9)+(5*6)+(4*2)+(3*0)+(2*1)+(1*6)=159
