143249-22-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 143249-22-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,3,2,4 and 9 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 143249-22:
(8*1)+(7*4)+(6*3)+(5*2)+(4*4)+(3*9)+(2*2)+(1*2)=113
113 % 10 = 3
So 143249-22-3 is a valid CAS Registry Number.
