143920-57-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 143920-57-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,3,9,2 and 0 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 143920-57:
(8*1)+(7*4)+(6*3)+(5*9)+(4*2)+(3*0)+(2*5)+(1*7)=124
124 % 10 = 4
So 143920-57-4 is a valid CAS Registry Number.
