Check Digit Verification of cas no

The CAS Registry Mumber 1065544-48-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,6,5,5,4 and 4 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1065544-48:
(9*1)+(8*0)+(7*6)+(6*5)+(5*5)+(4*4)+(3*4)+(2*4)+(1*8)=150
150 % 10 = 0
So 1065544-48-0 is a valid CAS Registry Number.

Highly efficient synthesis of polysubstituted fluorene via iron-catalyzed intramolecular Friedel-Crafts alkylation of biaryl alcohols

Sarkar, Soumen,Maiti, Sukhendu,Bera, Krishnendu,Jalal, Swapnadeep,Jana, Umasish

, p. 5544 - 5547 (2012/11/07)

An efficient and mild Fe(III)-catalyzed intramolecular Friedel-Crafts alkylation of biaryl methanol derivatives has been developed to achieve the substituted fluorene derivatives. The present reaction provides an excellent alternative to published methods

Potentially Aromatic Thiophenium Ylides. V. Reactions of Ethoxycarbonyl- (and Methoxycarbonyl)-2-(2-thienyl)phenylcarbene

Solbakken, Magne,Skramstad, Jan

, p. 1214 - 1220 (2007/10/02)

In an attempt to make thiophenium ylides in which the ylide bond is part of a five-membered ring annulated to the α-side of the thiophene moiety, two alkoxycarbonyl substituted 2-(2-thienyl)phenylcarbenes have been made, with and without chlorine substituents in the remaining thiophene positions.With rhodium acetate as a catalyst the carbene without chlorines cyclized to the 3-position of the thiophene to give a fluorene analogue, whereas no cyclization was detected when the 3-position was blocked.
