173259-64-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 173259-64-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,3,2,5 and 9 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 173259-64:
(8*1)+(7*7)+(6*3)+(5*2)+(4*5)+(3*9)+(2*6)+(1*4)=148
148 % 10 = 8
So 173259-64-8 is a valid CAS Registry Number.
