111217-99-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 111217-99-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,1,2,1 and 7 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 111217-99:
(8*1)+(7*1)+(6*1)+(5*2)+(4*1)+(3*7)+(2*9)+(1*9)=83
83 % 10 = 3
So 111217-99-3 is a valid CAS Registry Number.
