Check Digit Verification of cas no
The CAS Registry Mumber 189251-12-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,9,2,5 and 1 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 189251-12:
(8*1)+(7*8)+(6*9)+(5*2)+(4*5)+(3*1)+(2*1)+(1*2)=155
155 % 10 = 5
So 189251-12-5 is a valid CAS Registry Number.
