Check Digit Verification of cas no
The CAS Registry Mumber 718578-05-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 7,1,8,5,7 and 8 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 718578-05:
(8*7)+(7*1)+(6*8)+(5*5)+(4*7)+(3*8)+(2*0)+(1*5)=193
193 % 10 = 3
So 718578-05-3 is a valid CAS Registry Number.
