Check Digit Verification of cas no
The CAS Registry Mumber 60523-21-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,0,5,2 and 3 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 60523-21:
(7*6)+(6*0)+(5*5)+(4*2)+(3*3)+(2*2)+(1*1)=89
89 % 10 = 9
So 60523-21-9 is a valid CAS Registry Number.

Enzyme-mediated optical resolution of 2-methyl-3,4-pentadien-1-ol, a chiral building block possessing terminal allenyl group
Konegawa, Tadayoshi,Ohtsuka, Yoshikazu,Ikeda, Hajime,Sugai, Takeshi,Ohta, Hiromichi
, p. 1297 - 1299 (1997)
Both enantiomers (>95% e.e.) of 2-methyl-3,4-pentadien-1-ol, a chiral building block possessing a terminal allenyl group were prepared via the two-stage enzymatic kinetic resolution, i.e., a sequence of lipase-catalyzed acetylation (Pseudomonas cepacia) and hydrolysis (Candida antarctica).
Synthesis of two nuphar alkaloids by allenic hydroxylamine cyclisation

scheme or table, p. 866 - 868 (2010/06/11)
A highly diastereoselective silver-catalysed cyclisation of a 2-substituted β-allenic hydroxylamine is reported. The resulting trans-isoxazolidine is converted into two Nuphar alkaloids by a sequence involving cross-metathesis and intramolecular reductive amination. Georg Thieme Verlag Stuttgart - New York.
Silver(I)-catalyzed aminocyclization of 2,3-butadienyl and 3,4-pentadienyl carbamates: An efficient and stereoselective synthesis of 4-vinyl-2-oxazolidinones and 4-vinyltetrahydro-2H-1,3-oxazin-2-ones
Kimura,Tanaka,Tamaru
, p. 1689 - 1705 (2007/10/02)
Silver(I) salts in combination with an appropriate base (mostly triethylamine) catalyzed the aminocyclization of N-substituted 2,3-butadienyl carbamates 1 (benzene, 50°C) to provide 4-vinyl-2-oxazolidinones 2 in good yields. The stereoselectivity (trans-2/cis-2) ranged from 1.4 for C5-Me to >30 for C5-phenyl, isopropenyl, and t-butyl derivatives. 3,4-Pentadienyl tosylcarbamates 3, the one-carbon higher homologues of 1, underwent a similar cyclization to give 4-vinyltetrahydro-2H-1,3-oxazin-2-one 4 in synthetically useful yields and in higher trans selectivities than 1.
