Check Digit Verification of cas no
The CAS Registry Mumber 18586-22-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,8,5,8 and 6 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 18586-22:
(7*1)+(6*8)+(5*5)+(4*8)+(3*6)+(2*2)+(1*2)=136
136 % 10 = 6
So 18586-22-6 is a valid CAS Registry Number.
