173606-52-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 173606-52-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,3,6,0 and 6 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 173606-52:
(8*1)+(7*7)+(6*3)+(5*6)+(4*0)+(3*6)+(2*5)+(1*2)=135
135 % 10 = 5
So 173606-52-5 is a valid CAS Registry Number.
