Check Digit Verification of cas no

The CAS Registry Mumber 40681-65-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,0,6,8 and 1 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 40681-65:
(7*4)+(6*0)+(5*6)+(4*8)+(3*1)+(2*6)+(1*5)=110
110 % 10 = 0
So 40681-65-0 is a valid CAS Registry Number.

A short expedient synthesis of [14C]Ticlopidine

Hickey, Michael J.,Kingston, Lee P.,Allen, Paul H.,Johnson, Tim,Wilkinson, David J.

, p. 172 - 174 (2014)

To support the development of a reactive metabolite strategy, the preparation of several radiolabelled compounds such as [14C] Ticlopidine was required. In this report, we describe a facile and rapid synthesis of [14C] Ticlopidine starting from [14C] carbon dioxide. The compound was radiolabelled in the 2-chloromethyl portion of the molecule with a specific activity of 53.4 mCi/mmol and with a radiochemical purity of 98.5%. Storage stability was best as the hydrochloride salt in an ethanol solution. Copyright
