Check Digit Verification of cas no
The CAS Registry Mumber 117143-88-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,7,1,4 and 3 respectively; the second part has 2 digits, 8 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 117143-88:
(8*1)+(7*1)+(6*7)+(5*1)+(4*4)+(3*3)+(2*8)+(1*8)=111
111 % 10 = 1
So 117143-88-1 is a valid CAS Registry Number.
