140231-68-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 140231-68-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,0,2,3 and 1 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 140231-68:
(8*1)+(7*4)+(6*0)+(5*2)+(4*3)+(3*1)+(2*6)+(1*8)=81
81 % 10 = 1
So 140231-68-1 is a valid CAS Registry Number.
