109923-84-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 109923-84-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,9,9,2 and 3 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 109923-84:
(8*1)+(7*0)+(6*9)+(5*9)+(4*2)+(3*3)+(2*8)+(1*4)=144
144 % 10 = 4
So 109923-84-4 is a valid CAS Registry Number.
