713093-45-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 713093-45-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 7,1,3,0,9 and 3 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 713093-45:
(8*7)+(7*1)+(6*3)+(5*0)+(4*9)+(3*3)+(2*4)+(1*5)=139
139 % 10 = 9
So 713093-45-9 is a valid CAS Registry Number.
