Check Digit Verification of cas no
The CAS Registry Mumber 18363-10-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,8,3,6 and 3 respectively; the second part has 2 digits, 1 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 18363-10:
(7*1)+(6*8)+(5*3)+(4*6)+(3*3)+(2*1)+(1*0)=105
105 % 10 = 5
So 18363-10-5 is a valid CAS Registry Number.
