Check Digit Verification of cas no
The CAS Registry Mumber 109613-90-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,9,6,1 and 3 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 109613-90:
(8*1)+(7*0)+(6*9)+(5*6)+(4*1)+(3*3)+(2*9)+(1*0)=123
123 % 10 = 3
So 109613-90-3 is a valid CAS Registry Number.
