130115-99-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 130115-99-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,0,1,1 and 5 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 130115-99:
(8*1)+(7*3)+(6*0)+(5*1)+(4*1)+(3*5)+(2*9)+(1*9)=80
80 % 10 = 0
So 130115-99-0 is a valid CAS Registry Number.
