Check Digit Verification of cas no

The CAS Registry Mumber 157664-05-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,7,6,6 and 4 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 157664-05:
(8*1)+(7*5)+(6*7)+(5*6)+(4*6)+(3*4)+(2*0)+(1*5)=156
156 % 10 = 6
So 157664-05-6 is a valid CAS Registry Number.

An Efficient General Route to Furo-, Pyrido- and Thieno-benzazepines via Pd0 Catalysed Cross Coupling Reactions and Nitrile Ylide Cyclisations

Finch, Harry,Reece, Donald H.,Sharp, John T.

, p. 1193 - 1204 (2007/10/02)

The cyclisation of diene-conjugated nitrile ylides of the general type 1, in which the conjugated system consists of a benzene ring and a five- or a six-membered heterocyclic ring, provides an effective route to fully unsaturated heterocyclobenzazepines.The combination of this cyclisation with a direct route to the nitrile ylide precursors via Pd0 catalysed cross-coupling gives an efficient general synthetic route to these systems from readily available starting materials.
