115580-84-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 115580-84-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,5,5,8 and 0 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 115580-84:
(8*1)+(7*1)+(6*5)+(5*5)+(4*8)+(3*0)+(2*8)+(1*4)=122
122 % 10 = 2
So 115580-84-2 is a valid CAS Registry Number.
