Check Digit Verification of cas no
The CAS Registry Mumber 122012-99-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,2,0,1 and 2 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 122012-99:
(8*1)+(7*2)+(6*2)+(5*0)+(4*1)+(3*2)+(2*9)+(1*9)=71
71 % 10 = 1
So 122012-99-1 is a valid CAS Registry Number.
