1582740-94-0 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1582740-94-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,5,8,2,7,4 and 0 respectively; the second part has 2 digits, 9 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1582740-94:
(9*1)+(8*5)+(7*8)+(6*2)+(5*7)+(4*4)+(3*0)+(2*9)+(1*4)=190
190 % 10 = 0
So 1582740-94-0 is a valid CAS Registry Number.

β-Hydroxy-γ-lactones as nucleophiles in the Nicholas reaction for the synthesis of oxepene rings. Enantioselective formal synthesis of (-)-isolaurepinnacin and (+)-rogioloxepane A

Rodriguez-Lopez, Julio,Ortega, Nuria,Martin, Victor S.,Martin, Tomas

, p. 3685 - 3688 (2014)

The enantioselective formal synthesis of (-)-isolaurepinnacin and (+)-rogioloxepane A has been achieved. The key steps are an intermolecular Nicholas reaction with a β-hydroxy-γ-lactone as the nucleophile, to form branched linear ethers, and an olefin ring-closing metathesis to obtain the oxepene core.
