Check Digit Verification of cas no

The CAS Registry Mumber 286957-61-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,8,6,9,5 and 7 respectively; the second part has 2 digits, 6 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 286957-61:
(8*2)+(7*8)+(6*6)+(5*9)+(4*5)+(3*7)+(2*6)+(1*1)=207
207 % 10 = 7
So 286957-61-7 is a valid CAS Registry Number.

Preparation of remacemide hydrochloride labelled with carbon-14, carbon-13, deuterium and tritium

Coombs,Dawson,Fedorchuk,Kingston,Lockley,Mather,McLachlan,Morlin,Spink,Wilkinson

, p. 533 - 543 (2007/10/03)

The anti-epileptic agent remacemide hydrochloride has been prepared labelled with 14C, from [carbonyl-14C]acetophenone, and with 13C from [13C6]benzene, [1,2-13C]acetyl chloride and [1-13C]glycine. [2-3H]Glycine was utilised to prepare remacemide labelled with tritium at low specific activity. In addition other 2H- and high specific activity 3H-isotopomers of the drug, and of an active metabolite of the drug, were prepared by hydrogen isotope exchange methodology. The R-12C/S-14C and S-12C/R-14C pseudoracemic drugs were also prepared by a synthesis involving resolution of a 14C-labelled amine intermediate via fractional crystallisation of the dibenzoyltartrate salts.
