130944-52-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 130944-52-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,0,9,4 and 4 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 130944-52:
(8*1)+(7*3)+(6*0)+(5*9)+(4*4)+(3*4)+(2*5)+(1*2)=114
114 % 10 = 4
So 130944-52-4 is a valid CAS Registry Number.
