115191-89-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 115191-89-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,5,1,9 and 1 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 115191-89:
(8*1)+(7*1)+(6*5)+(5*1)+(4*9)+(3*1)+(2*8)+(1*9)=114
114 % 10 = 4
So 115191-89-4 is a valid CAS Registry Number.
