Check Digit Verification of cas no
The CAS Registry Mumber 123099-07-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,3,0,9 and 9 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 123099-07:
(8*1)+(7*2)+(6*3)+(5*0)+(4*9)+(3*9)+(2*0)+(1*7)=110
110 % 10 = 0
So 123099-07-0 is a valid CAS Registry Number.
