115259-92-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 115259-92-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,5,2,5 and 9 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 115259-92:
(8*1)+(7*1)+(6*5)+(5*2)+(4*5)+(3*9)+(2*9)+(1*2)=122
122 % 10 = 2
So 115259-92-2 is a valid CAS Registry Number.
