82830-36-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 82830-36-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,2,8,3 and 0 respectively; the second part has 2 digits, 3 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 82830-36:
(7*8)+(6*2)+(5*8)+(4*3)+(3*0)+(2*3)+(1*6)=132
132 % 10 = 2
So 82830-36-2 is a valid CAS Registry Number.

Preparation of 2'-13c-l-histidine starting from 13c-thiocyanate: Synthetic access to any site-directed stable isotope enriched l-histidine

Talab, Sarra,Taha, Kamal Khalifa,Lugtenburg, Johan

, p. 1023 - 1033 (2014/02/14)

1-Benzyl-2-(methylthio)-imidazole-5-ketone is obtained in a few simple steps starting from thiocyanate and glycine amide (glycin). Subsequent treatment with diethyl phosphorocyanidate and functional group manipulations gives 1-benzyl-5-chloromethylimidazolium chloride. This compound is converted under mild O'Donnell conditions into the corresponding L-histidine derivative. After deprotection L-histidine is obtained in good yield and 99% enantiomeric excess. 2'-13C-L-Histidine has been obtained via this new scheme with high (99%) 13C incorporation starting with commercially available 13C- thiocyanate. This synthetic scheme allows access to any isotopomer of L-histidine and many other biologically important imidazole derivatives.
