131189-11-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 131189-11-2 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, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 131189-11:
(8*1)+(7*3)+(6*1)+(5*1)+(4*8)+(3*9)+(2*1)+(1*1)=102
102 % 10 = 2
So 131189-11-2 is a valid CAS Registry Number.
