Check Digit Verification of cas no
The CAS Registry Mumber 172506-24-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,2,5,0 and 6 respectively; the second part has 2 digits, 2 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 172506-24:
(8*1)+(7*7)+(6*2)+(5*5)+(4*0)+(3*6)+(2*2)+(1*4)=120
120 % 10 = 0
So 172506-24-0 is a valid CAS Registry Number.
