130749-40-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 130749-40-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,0,7,4 and 9 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 130749-40:
(8*1)+(7*3)+(6*0)+(5*7)+(4*4)+(3*9)+(2*4)+(1*0)=115
115 % 10 = 5
So 130749-40-5 is a valid CAS Registry Number.
