Check Digit Verification of cas no

The CAS Registry Mumber 122889-63-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,2,8,8 and 9 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 122889-63:
(8*1)+(7*2)+(6*2)+(5*8)+(4*8)+(3*9)+(2*6)+(1*3)=148
148 % 10 = 8
So 122889-63-8 is a valid CAS Registry Number.

Cycloaddition of carbonyl ylides to isatins: Synthesis of novel spiro oxindoles

Nair,Sheela,Sethumadhavan,Bindu,Rath,Eigendorf

, p. 272 - 274 (2001)

Facile dipolar cycloaddition reactions of isatins with carbonyl ylides, generated by Rh2(OAc)4 catalyzed reaction of α-diazo ketones yielding novel spiro oxindole derivatives are described.

Tandem Cyclization-Cycloaddition Reaction of Rhodium Carbenoids. Studies Dealing with the Geometric Requirements of Dipole Formation

Padwa, Albert,Chinn, Richard L.,Hornbuckle, Susan F.,Zhang, Zhijia J.

, p. 3271 - 3278 (2007/10/02)

The carbenoid intermediate derived by the treatment of several 1-diazabutadienediones with rhodium(II) acetate undergoes ready transannular cyclization onto the neighboring keto group to give five-membered ring carbonyl ylides.The dipole derived from ethy

CYCLIC CARBONYL YLIDE FORMATION FROM THE RHODIUM (II) ACETATE CATALYZED REACTION OF 1-DIAZOALKANEDIONES

Padwa, Albert,Chinn, Richard L.,Hornblucke, Susan F.,Zhi, Lin

, p. 301 - 304 (2007/10/02)

Treatment of 1-diazoalkanediones with rhodium (II) acetate results in cyclization of the intermediate rhodium carbenoid to give a cyclic carbonyl ylide which readily undergoes bimolecular dipolar cycloaddition with various dipolarophiles.
