130815-72-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 130815-72-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,0,8,1 and 5 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 130815-72:
(8*1)+(7*3)+(6*0)+(5*8)+(4*1)+(3*5)+(2*7)+(1*2)=104
104 % 10 = 4
So 130815-72-4 is a valid CAS Registry Number.
