717132-49-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 717132-49-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 7,1,7,1,3 and 2 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 717132-49:
(8*7)+(7*1)+(6*7)+(5*1)+(4*3)+(3*2)+(2*4)+(1*9)=145
145 % 10 = 5
