120517-40-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 120517-40-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,0,5,1 and 7 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 120517-40:
(8*1)+(7*2)+(6*0)+(5*5)+(4*1)+(3*7)+(2*4)+(1*0)=80
80 % 10 = 0
So 120517-40-0 is a valid CAS Registry Number.
