Check Digit Verification of cas no

The CAS Registry Mumber 171356-57-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,1,3,5 and 6 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 171356-57:
(8*1)+(7*7)+(6*1)+(5*3)+(4*5)+(3*6)+(2*5)+(1*7)=133
133 % 10 = 3
So 171356-57-3 is a valid CAS Registry Number.

Control over absolute (R,S), relative (syn,anti) and geometrical (E,Z) stereochemistry in the synthesis of allylically substituted alkenes from diphenylphosphinoyl epoxy alcohols

Clayden, Jonathan,McElroy, Andrew B.,Warren, Stuart

, p. 1913 - 1934 (2007/10/02)

Regioselective ring-openings of epoxy alcohols bearing a diphenylphosphinoyl (Ph2PO) group give diols which can undergo stereospecific Horner-Wittig elimination.This method was used to make allylic alcohols, unsaturated β-hydroxy sulfides, homoallylic alcohols and unsaturated amino acids, with control over their absolute (R,S), relative (syn,anti) and geometrical (E,Z) stereochemistry.

Stereocontrolled Synthesis of R or S, E or Z Unsaturated α-Amino Acids by Enantio- and Diastereoselective Epoxidation of δ-Hydroxy Allylic Phosphine Oxides

Clayden, Jonathan,Collington, Eric W.,Warren, Stuart
