Check Digit Verification of cas no
The CAS Registry Mumber 181526-16-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,1,5,2 and 6 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 181526-16:
(8*1)+(7*8)+(6*1)+(5*5)+(4*2)+(3*6)+(2*1)+(1*6)=129
129 % 10 = 9
So 181526-16-9 is a valid CAS Registry Number.
