Check Digit Verification of cas no
The CAS Registry Mumber 172025-45-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,2,0,2 and 5 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 172025-45:
(8*1)+(7*7)+(6*2)+(5*0)+(4*2)+(3*5)+(2*4)+(1*5)=105
105 % 10 = 5
So 172025-45-5 is a valid CAS Registry Number.
