Check Digit Verification of cas no

The CAS Registry Mumber 1286255-67-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,8,6,2,5 and 5 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1286255-67:
(9*1)+(8*2)+(7*8)+(6*6)+(5*2)+(4*5)+(3*5)+(2*6)+(1*7)=181
181 % 10 = 1
So 1286255-67-1 is a valid CAS Registry Number.

A catalytic asymmetric chlorocyclization of unsaturated amides

Jaganathan, Arvind,Garzan, Atefeh,Whitehead, Daniel C.,Staples, Richard J.,Borhan, Babak

, p. 2593 - 2596 (2011/05/02)

The asymmetric chlorocyclization of unsaturated amides catalyzed by (DHQD)2PHAL yields oxazoline and dihydrooxazine derivatives (see scheme). The reaction is operationally simple and employs 1-2 mol % of the commercially available (DHQD)2PHAL (hydroquinidine 1,4-phthalazinediyl diether) catalyst. Different substitution patterns of the olefin as well as aromatic and aliphatic olefin substituents are well tolerated. DCDPH=N,N-dichloro-5,5-diphenylhydantoin. Copyright
