130509-58-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 130509-58-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,0,5,0 and 9 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 130509-58:
(8*1)+(7*3)+(6*0)+(5*5)+(4*0)+(3*9)+(2*5)+(1*8)=99
99 % 10 = 9
So 130509-58-9 is a valid CAS Registry Number.
