143468-22-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 143468-22-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,3,4,6 and 8 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 143468-22:
(8*1)+(7*4)+(6*3)+(5*4)+(4*6)+(3*8)+(2*2)+(1*2)=128
128 % 10 = 8
So 143468-22-8 is a valid CAS Registry Number.
