131189-27-0 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 131189-27-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,1,1,8 and 9 respectively; the second part has 2 digits, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 131189-27:
(8*1)+(7*3)+(6*1)+(5*1)+(4*8)+(3*9)+(2*2)+(1*7)=110
110 % 10 = 0
So 131189-27-0 is a valid CAS Registry Number.
