5172-50-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 5172-50-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,1,7 and 2 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 5172-50:
(6*5)+(5*1)+(4*7)+(3*2)+(2*5)+(1*0)=79
79 % 10 = 9
