143141-90-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 143141-90-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,3,1,4 and 1 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 143141-90:
(8*1)+(7*4)+(6*3)+(5*1)+(4*4)+(3*1)+(2*9)+(1*0)=96
96 % 10 = 6
So 143141-90-6 is a valid CAS Registry Number.
