Check Digit Verification of cas no
The CAS Registry Mumber 179104-42-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,9,1,0 and 4 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 179104-42:
(8*1)+(7*7)+(6*9)+(5*1)+(4*0)+(3*4)+(2*4)+(1*2)=138
138 % 10 = 8
So 179104-42-8 is a valid CAS Registry Number.
