Check Digit Verification of cas no
The CAS Registry Mumber 33846-96-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,3,8,4 and 6 respectively; the second part has 2 digits, 9 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 33846-96:
(7*3)+(6*3)+(5*8)+(4*4)+(3*6)+(2*9)+(1*6)=137
137 % 10 = 7
So 33846-96-7 is a valid CAS Registry Number.

Organic Syntheses via Transition Metal Complexes, 60. - Novel Type of Benzoannelation with Carbene Complexes and Alkynes. - 2-Oxybenzoannelation of Cycloheptatriene via (Cycloheptatrienylmethyl)carbene Complexes of Chromium and Tungsten

We report on a three-step procedure for the regiospecific 2-oxybenzoannelation to cycloheptatriene by means of Fischer carbene complexes and alkynes.The first step involves the formation of (cycloheptatrienylmethyl)carbene complexes LnM=C(OEt)-CH2-c-C7H7 nM = Cr(CO)5 (a), W(CO)5 (b)> from the corresponding methylcarbene complexes and a tropylium salt. 1 reacts with the alkyne Et2N-CC-Me (2) to give the (E)- and (Z)-1-amino(1-alkenyl)carbene comlexes LnM=C(NEt2)-C(Me)=C(OEt)-CH2-c-C7J7 (3 and 4 resp.).Thermolysis of 3b n = W(CO)5, 100 deg C, 5 h> finally leads to elimination of W(CO)5(Et2NH) (6b) and the regiospecific formation of ethoxybenzocycloheptatrienes 5, 7, and 8 in 92percent total yield.The reaction is kinetically controlled and yields an isomeric ratio of 5:7:8 = 60:12:20percent with the thermodynamically less stable isomer 5 predominating.
