Check Digit Verification of cas no
The CAS Registry Mumber 10576-12-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,0,5,7 and 6 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 10576-12:
(7*1)+(6*0)+(5*5)+(4*7)+(3*6)+(2*1)+(1*2)=82
82 % 10 = 2
So 10576-12-2 is a valid CAS Registry Number.

Diastereoselectivity and Reactivity in the Diels-Alder Reactions of α-Chloronitroso Ethers
Felber, Helena,Kresze, Guenter,Prewo, Roland,Vasella, Andrea
, p. 1137 - 1146 (2007/10/02)
The structure of the α-chloronitroso ether 1, obtained from the hydroximolactone 2 and tert-butyl hypochlorite (89percent), was established by X-ray crystallographic analysis.The cycloadditions of 1 with dienes 3 and 8-11 led to the N-unsubstituted 3,6-dihydro-2H-1,2-oxazines 6 and 12-16 in high enantiomeric excess (Table 1).Due to the additional α-alkoxy group, the reactivity of 2 is much superior to the one of known α-chloronitrosoalkanes.The reactive conformation of 1 was deduced from the X-ray analysis as well as the high diastereoselectivity of the cycloadditions.The importance of the α-alkoxy group was evidenced from the similar reactivity of the racemic α-chloronitroso ethers 25-27 which were prepared from the hydroximo ethers 28-30 and tert-butyl hypochlorite.
