807616-80-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 807616-80-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,0,7,6,1 and 6 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 807616-80:
(8*8)+(7*0)+(6*7)+(5*6)+(4*1)+(3*6)+(2*8)+(1*0)=174
174 % 10 = 4
So 807616-80-4 is a valid CAS Registry Number.

Syntheses of trans -SCH-A and cis -SCH-A via a stereodivergent cyclopropanation protocol

Csatayova, Kristina,Davies, Stephen G.,Lee, James A.,Ling, Kenneth B.,Roberts, Paul M.,Russell, Angela J.,Thomson, James E.

supporting information; experimental part, p. 3152 - 3155 (2010/09/05)

(Figure Presented) A highly diastereoselective cyclopropanation protocol has been employed in the syntheses of trans-SCH-A and cis-SCH-A. This strategy encompasses a stereodivergent procedure for the preparation of syn- and anti-cyclopropane diastereoisom

Oxidative rearrangement of tertiary allylic alcohols employing oxoammonium salts

Shibuya, Masatoshi,Tomizawa, Masaki,Iwabuchi, Yoshiharu

, p. 4750 - 4752 (2008/09/20)

(Chemical Equation Presented) Practical and highly efficient methods for oxidative rearrangement of tertiary allylic alcohols to β-substituted α,β-unsaturated carbonyl compounds employing oxoammonium salts are described. The methods developed are applicable to acyclic substrates as well as medium membered ring substrates and macrocyclic substrates. The counteranion of the oxoammonium salt plays crucial roles on this oxidative rearrangement.
