143137-32-0 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 143137-32-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,3,1,3 and 7 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 143137-32:
(8*1)+(7*4)+(6*3)+(5*1)+(4*3)+(3*7)+(2*3)+(1*2)=100
100 % 10 = 0
So 143137-32-0 is a valid CAS Registry Number.
