Check Digit Verification of cas no

The CAS Registry Mumber 1160457-28-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,6,0,4,5 and 7 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1160457-28:
(9*1)+(8*1)+(7*6)+(6*0)+(5*4)+(4*5)+(3*7)+(2*2)+(1*8)=132
132 % 10 = 2
So 1160457-28-2 is a valid CAS Registry Number.

Rhodium-catalyzed intramolecular cyclization of naphthol- or phenol-linked 1,6-enynes through the cleavage and formation of sp2 C-O bonds

Sakiyama, Norifumi,Noguchi, Keiichi,Tanaka, Ken

, p. 5976 - 5980 (2012/07/03)

Put a ring on it: A cationic rhodium(I)/binap complex catalyzes the intramolecular cyclization reactions of naphthol- or phenol-linked 1,6-enynes to produce vinylnaphtho- or vinylbenzofurans and vinylnaphtho- or vinylbenzopyrans through the cleavage and f

Nazarov cyclization initiated by peracid oxidation: The total synthesis of (±)-rocaglamide

Malona, John A.,Cariou, Kevin,Frontier, Alison J.

supporting information; experimental part, p. 7560 - 7561 (2009/10/17)

(Chemical Equation Presented) The total syntheses of aglafolin, rocagloic acid, and rocaglamide using Nazarov cyclization are described. Generation of the necessary oxyallyl cation intermediate was accomplished via peracid oxidation of an allenol ether to generate an unusual oxycarbeniumion species that undergoes cyclization. The synthesis is efficient, hig hly diastereoselective, and strategically distinct from previous syntheses of rocaglamide.
