130749-19-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 130749-19-8 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, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 130749-19:
(8*1)+(7*3)+(6*0)+(5*7)+(4*4)+(3*9)+(2*1)+(1*9)=118
118 % 10 = 8
So 130749-19-8 is a valid CAS Registry Number.
