118080-50-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 118080-50-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,8,0,8 and 0 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 118080-50:
(8*1)+(7*1)+(6*8)+(5*0)+(4*8)+(3*0)+(2*5)+(1*0)=105
105 % 10 = 5
So 118080-50-5 is a valid CAS Registry Number.
