Check Digit Verification of cas no
The CAS Registry Mumber 174874-23-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,4,8,7 and 4 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 174874-23:
(8*1)+(7*7)+(6*4)+(5*8)+(4*7)+(3*4)+(2*2)+(1*3)=168
168 % 10 = 8
So 174874-23-8 is a valid CAS Registry Number.
