115890-44-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 115890-44-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,5,8,9 and 0 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 115890-44:
(8*1)+(7*1)+(6*5)+(5*8)+(4*9)+(3*0)+(2*4)+(1*4)=133
133 % 10 = 3
So 115890-44-3 is a valid CAS Registry Number.

Enantioselective synthesis of (-)-kainic acid
Takano,Sugihara,Satoh,Ogasawara
, p. 6467 - 6471 (2007/10/02)
Novel diastereoselectivity in the intramolecular Diels-Alder reaction of the heterodiene 18 has been observed. The structure of the cycloadduct was determined to be 20, possessing cis-5/6 ring juncture by converting it into (-)-kainic acid and kainic acid lactone.
