111222-49-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 111222-49-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,1,2,2 and 2 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 111222-49:
(8*1)+(7*1)+(6*1)+(5*2)+(4*2)+(3*2)+(2*4)+(1*9)=62
62 % 10 = 2
So 111222-49-2 is a valid CAS Registry Number.
