24892-82-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 24892-82-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,4,8,9 and 2 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 24892-82:
(7*2)+(6*4)+(5*8)+(4*9)+(3*2)+(2*8)+(1*2)=138
138 % 10 = 8
So 24892-82-8 is a valid CAS Registry Number.

Stereocontrolled synthesis of carbon-carbon double bond locked analogues of strobilurins which are characterized by a trans-1,2-disubstituted cyclopropane ring

Rossi,Carpita,Ribecai,Mannina

, p. 2847 - 2856 (2001)

The racemic forms of four new carbon-carbon double bond locked analogues of strobilurins, which are characterized by a trans-1,2-disubstituted cyclopropane ring, have been synthesized according to a strategy which involves palladium-catalyzed cross-coupli

Enantioselective synthesis of 1-aminoindene derivativesviaasymmetric Br?nsted acid catalysis

Ding, Du,Jiang, Hua-Jie,Wang, Tao,Wu, Xiang,Zhang, Ying,Zhao, Li-Ping

supporting information, p. 9680 - 9683 (2021/09/30)

We describe a catalytic asymmetric iminium ion cyclization reaction of simple 2-alkenylbenzaldimines using a BINOL-derived chiralN-triflyl phosphoramide. The corresponding 1-aminoindenes and tetracyclic 1-aminoindanes are formed in good yields and high enantioselectivities. Further, the chemical utility of the obtained enantiopure 1-aminoindene is demonstrated for the asymmetric synthesis of (S)-rasagiline.
