117130-01-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 117130-01-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,7,1,3 and 0 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 117130-01:
(8*1)+(7*1)+(6*7)+(5*1)+(4*3)+(3*0)+(2*0)+(1*1)=75
75 % 10 = 5
So 117130-01-5 is a valid CAS Registry Number.
