Check Digit Verification of cas no

The CAS Registry Mumber 1235447-22-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,3,5,4,4 and 7 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1235447-22:
(9*1)+(8*2)+(7*3)+(6*5)+(5*4)+(4*4)+(3*7)+(2*2)+(1*2)=139
139 % 10 = 9
So 1235447-22-9 is a valid CAS Registry Number.

Basic techniques of working on a solid phase: From ABC of the peptide synthesis to libraries of non-natural amino acids

Babaev,Ermolat'ev

experimental part, p. 2572 - 2589 (2011/04/15)

Libraries of hardly available amino acids bearing a heteroaromatic ring (2-pyrimidyl, substituted 2-pyridyl or 2-thiazolyl) at the amino group were prepared using solid-phase synthesis on various resins. The synthesized compounds are structurally similar to some known antidiabetic drugs. The paper combines features of a review (elementary introduction to the solid-phase synthesis methodology and technique for beginners and selected methods from peptide chemistry) and step-by-step experimental protocols (tested by the authors) useful as a methodic tool. The presented protocols (immobilization and modification of amino acids, placing and removal of common protective groups) require no sophisticated equipment and may be useful as pictorial introductory tasks for students education.
