Check Digit Verification of cas no
The CAS Registry Mumber 90109-12-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,0,1,0 and 9 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 90109-12:
(7*9)+(6*0)+(5*1)+(4*0)+(3*9)+(2*1)+(1*2)=99
99 % 10 = 9
So 90109-12-9 is a valid CAS Registry Number.
