Check Digit Verification of cas no

The CAS Registry Mumber 1643360-03-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,4,3,3,6 and 0 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1643360-03:
(9*1)+(8*6)+(7*4)+(6*3)+(5*3)+(4*6)+(3*0)+(2*0)+(1*3)=145
145 % 10 = 5
So 1643360-03-5 is a valid CAS Registry Number.

Regiocontrolled palladium-catalyzed and copper-mediated C-H bond functionalization of protected l-histidine

Mahindra, Amit,Jain, Rahul

, p. 3792 - 3796 (2014/06/09)

We describe the controlled and regioselective transition-metal-catalyzed C-H bond arylation of protected l-histidine with aryl halides as the coupling partner. Using this approach, a large number of C-2 arylated l-histidines have been synthesized with diverse substitutions bearing electron-donating and electron-withdrawing groups, in good to excellent yields. These synthetic amino acids possessing dual hydrophobic-hydrophilic character are important synthons of bioactive peptidomimetics, which are imperative potent inhibitors of Cryptococcus neoformans. This journal is the Partner Organisations 2014.
