Check Digit Verification of cas no
The CAS Registry Mumber 53173-70-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,3,1,7 and 3 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 53173-70:
(7*5)+(6*3)+(5*1)+(4*7)+(3*3)+(2*7)+(1*0)=109
109 % 10 = 9
So 53173-70-9 is a valid CAS Registry Number.
