Check Digit Verification of cas no
The CAS Registry Mumber 109579-23-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,9,5,7 and 9 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 109579-23:
(8*1)+(7*0)+(6*9)+(5*5)+(4*7)+(3*9)+(2*2)+(1*3)=149
149 % 10 = 9
So 109579-23-9 is a valid CAS Registry Number.
