Check Digit Verification of cas no

The CAS Registry Mumber 1228293-95-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,2,8,2,9 and 3 respectively; the second part has 2 digits, 9 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1228293-95:
(9*1)+(8*2)+(7*2)+(6*8)+(5*2)+(4*9)+(3*3)+(2*9)+(1*5)=165
165 % 10 = 5
So 1228293-95-5 is a valid CAS Registry Number.

Stereoselective total synthesis of (+)-(6R,2′S)-cryptocaryalactone and (-)-(6S,2′S)-epi cryptocaryalactone via asymmetric acetate aldol reaction

Yadav,Bhunia, Dinesh C.,Ganganna

, p. 2496 - 2499 (2012/06/16)

The total synthesis of (+)-(6R,2′S)-cryptocaryalactone and (-)-(6S,2′S)-epi cryptocaryalactone is reported based on asymmetric acetate aldol reaction. Still-Gennari reaction, Evans acetal intramolecular oxa-Michael reaction and lactonisation are the key s

A concise total synthesis of (+)-neopeltolide

Fuwa, Haruhiko,Saito, Asami,Sasaki, Makoto

supporting information; experimental part, p. 3041 - 3044 (2010/07/05)

(Figure Presented) Short and sweet: The highly potent antiproliferative marine macrolide (+)-neopeltolide has been synthesized based on the strategic application of olefin metathesis reactions. The total synthesis proceeded in only 13 steps from commercially available starting materials, and represents the shortest synthesis of (+)-neopeltolide reported to date.
