1173208-80-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1173208-80-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,7,3,2,0 and 8 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1173208-80:
(9*1)+(8*1)+(7*7)+(6*3)+(5*2)+(4*0)+(3*8)+(2*8)+(1*0)=134
134 % 10 = 4
So 1173208-80-4 is a valid CAS Registry Number.
