1186503-21-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1186503-21-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,8,6,5,0 and 3 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1186503-21:
(9*1)+(8*1)+(7*8)+(6*6)+(5*5)+(4*0)+(3*3)+(2*2)+(1*1)=148
148 % 10 = 8
So 1186503-21-8 is a valid CAS Registry Number.

Synthesis of a Range of Polyhydroxy 8-Aryl Flavones

Larsen, Lesley,Yoon, Dong Hee,Weavers, Rex T.

, p. 2935 - 2948 (2009)

The 8-iodo flavones formed by cyclization of benzyl-protected chalcones with iodine in dimethyl sulfoxide have been transformed by a Suzuki coupling reaction into a variety of 8-aryl derivatives. Deprotection with boron tribromide has generated a family of new 8-aryl flavones containing four to eight hydroxyl groups.
