Check Digit Verification of cas no

The CAS Registry Mumber 67436-13-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,7,4,3 and 6 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 67436-13:
(7*6)+(6*7)+(5*4)+(4*3)+(3*6)+(2*1)+(1*3)=139
139 % 10 = 9
So 67436-13-9 is a valid CAS Registry Number.

A comprehensive one-pot synthesis of protected cysteine and selenocysteine SPPS derivatives

Flemer, Stevenson

, p. 1257 - 1264 (2015/04/14)

A proof-of-principle methodology is presented in which all commercially-available cysteine (Cys) and selenocysteine (Sec) solid phase peptide synthesis (SPPS) derivatives are synthesized in high yield from easily prepared protected dichalcogenide precursors. A Zn-mediated biphasic reduction process applied to a series of four bis-Nα-protected dichalcogenide compounds allows facile conversion to their corresponding thiol and selenol intermediates followed by insitu S- or Se-alkylation with various electrophiles to directly access twenty one known Cys and Sec SPPS derivatives. Most of these derivatives were able to be precipitated in crude form out of petroleum ether in sufficient purity for direct use as peptide building blocks. Subsequent incorporation of these derivatives into peptide models nicely illustrates their viability and applicability toward SPPS.
