299185-07-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 299185-07-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,9,9,1,8 and 5 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 299185-07:
(8*2)+(7*9)+(6*9)+(5*1)+(4*8)+(3*5)+(2*0)+(1*7)=192
192 % 10 = 2
So 299185-07-2 is a valid CAS Registry Number.

Intermolecular [3+2] MIRC reactions with alkynoates. Asymmetric Michael addition leading to a nonracemic cyclopentene-annulated α,β-butenolide

Nakache, Philippe,Ghera, Eugene,Hassner, Alfred

, p. 5583 - 5587 (2000)

A novel Michael-initiated ring closure reacton involving allylic chlorosulfone (2) and γ-alkoxy-α,β-ynoates to afford 4- methylenecyclopentenecarboxylates is reported, while with γ-alkylynoates no reaction occurred. With chiral phenyl ynoates 4, the reaction proceeds by 1,3-asymmetric induction and leads further to a nonracemic annulated α,β- butenolide (7). (C) 2000 Elsevier Science Ltd.
