136266-34-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 136266-34-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,6,2,6 and 6 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 136266-34:
(8*1)+(7*3)+(6*6)+(5*2)+(4*6)+(3*6)+(2*3)+(1*4)=127
127 % 10 = 7
So 136266-34-7 is a valid CAS Registry Number.

Enantiospecific synthesis of the phospholipase A2 inhibitor (-)-cinatrin B

Cuzzupe, Anthony N.,Di Florio, Romina,Rizzacasa, Mark A.

, p. 4392 - 4398 (2002)

The first enantiospecific synthesis of phospholipase A2 (PLA2) inhibitor (-)-cinatrin B (2) from the D-arabinose derivative 9 is described. The spirolactone system was formed by an Ireland-Claisen rearrangement of the allyl ester 8 followed by hydrolysis and stereoselective iodolactonization. The stereoselectivity of the rearrangement was controlled by the asymmetry in the allylic alcohol fragment. Ester (S)-8 gave the desired rearrangement product 7 and the epimer 13 in high yield as a 73:27 ratio, respectively. The final stereocenter at C2 was introduced via a chelation-controlled addition of the Grignard reagent derived from trimethylsilylacetylene to α-hydroxy ketone 6. Transformation of the terminal alkyne into the methyl ester 21 followed by acetal hydrolysis and selective lactol oxidation afforded cinatrin B methyl ester (22). Base hydrolysis and acid-induced relactonization then gave (-)-cinatrin B (2).
