170960-25-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 170960-25-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,0,9,6 and 0 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 170960-25:
(8*1)+(7*7)+(6*0)+(5*9)+(4*6)+(3*0)+(2*2)+(1*5)=135
135 % 10 = 5
So 170960-25-5 is a valid CAS Registry Number.
