Check Digit Verification of cas no

The CAS Registry Mumber 135810-01-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,5,8,1 and 0 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 135810-01:
(8*1)+(7*3)+(6*5)+(5*8)+(4*1)+(3*0)+(2*0)+(1*1)=104
104 % 10 = 4
So 135810-01-4 is a valid CAS Registry Number.

An expedient large-scale preparation of a dibenz[b,e]oxepinone derivative

Lee, Thomas B.K.,Tebben, Andrew J.,Weiberth, Franz J.,Wong, George S.K.

, p. 747 - 751 (1998)

A convenient, large-scale synthesis of a dibenz[b,e]oxepinone derivative is described. The dibenz[-b,e]oxepinone ring system is constructed using an iron chloride catalyzed intramolecular Friedel-Crafts cyclization of an appropriate phenoxymethylbenzoic acid chloride in toluene, reagents and conditions that are economically and environmentally compatible with large- scale preparation.
