Check Digit Verification of cas no

The CAS Registry Mumber 137956-89-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,7,9,5 and 6 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 137956-89:
(8*1)+(7*3)+(6*7)+(5*9)+(4*5)+(3*6)+(2*8)+(1*9)=179
179 % 10 = 9
So 137956-89-9 is a valid CAS Registry Number.

Diastereoselective carbometalation of γ-heterosubstituted vinyl metals

Marek, Ilane,Lefrancois, Jean-Michel,Normant, Jean F.

, p. 910 - 918 (2007/10/02)

The allylzincation of various γ-heterosubstituted vinyl metals proceeds diastereoselectively.This represents a new synthetic approach to constructing two or three adjacent stereogenic centers in acyclic systems. - Keywords: carbometalation / 1,1-dimetalli

Acyclic stereocontrol through the metalla-Claisen rearrangement. Part II

Marek, Ilane,Normant, Jean F.

, p. 5973 - 5976 (2007/10/02)

The metalla-Claisen rearrangement reported here, leads to 1,1-dimetallic compounds where three asymmetric centers are obtained with good diastereoselection.
