Check Digit Verification of cas no
The CAS Registry Mumber 18556-07-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,8,5,5 and 6 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 18556-07:
(7*1)+(6*8)+(5*5)+(4*5)+(3*6)+(2*0)+(1*7)=125
125 % 10 = 5
So 18556-07-5 is a valid CAS Registry Number.
