Check Digit Verification of cas no
The CAS Registry Mumber 140173-18-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,0,1,7 and 3 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 140173-18:
(8*1)+(7*4)+(6*0)+(5*1)+(4*7)+(3*3)+(2*1)+(1*8)=88
88 % 10 = 8
So 140173-18-8 is a valid CAS Registry Number.
