Check Digit Verification of cas no

The CAS Registry Mumber 1212436-47-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,1,2,4,3 and 6 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1212436-47:
(9*1)+(8*2)+(7*1)+(6*2)+(5*4)+(4*3)+(3*6)+(2*4)+(1*7)=109
109 % 10 = 9
So 1212436-47-9 is a valid CAS Registry Number.

Highly lk-Selective Asymmetric Nitrile Oxide Cycloadditions to a C2-Symmetric 1,3-Diacryloyl-2,2-dimethylimidazolidine and 4-Chiral 3-Acryloyl-2,2-dialkyloxazolidines

Kanemasa, Shuji,Onimura, Kenjiro

, p. 8645 - 8658 (2007/10/02)

1,3-Dipolar cycloadditions of benzonitrile oxide to the acrylamides derived from a C2-symmetric 2,2-dimethylimidazolidine and 4-chiral 2,2-dialkyloxazolidines show high lk-diasteroselectivities.Easy separation of the major lk-isomers from the minor ul-diastereomers is followed by reductive removal of the chiral auxiliaries to produce optically pure 2-isoxazoline-5-methanols.Absolute diastereoselectivities were recorded in the nitrile oxide cycloadditions of 3-acryloyl-2,2-dialkyl-4-(diphenylmethyl)oxazolidines at 0 deg C.
