Check Digit Verification of cas no
The CAS Registry Mumber 142231-68-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,2,2,3 and 1 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 142231-68:
(8*1)+(7*4)+(6*2)+(5*2)+(4*3)+(3*1)+(2*6)+(1*8)=93
93 % 10 = 3
So 142231-68-3 is a valid CAS Registry Number.
