191605-39-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 191605-39-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,1,6,0 and 5 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 191605-39:
(8*1)+(7*9)+(6*1)+(5*6)+(4*0)+(3*5)+(2*3)+(1*9)=137
137 % 10 = 7
So 191605-39-7 is a valid CAS Registry Number.

The regiospecific synthesis of angularly-fused xanthones via the benzannulation of 1,2-adducts derived from 3-(o-anisoyl)-4-substituted cyclobutenediones and their dithianyl derivatives.

Sun, Lijun,Liebeskind, Lanny S.

, p. 3663 - 3666 (1997)

Described it, this paper is a new synthetic approach to angularlyl-fused and simpler substituted xanthones that is based upon the benzanullation of 2-(o-anisoyl)-4-heteroaryl-2-cyclobutenones and 2-(2-(o-anisyl)-1,3-dithian-2-yl)-4-alkenyl-2- cyclobutenones followed by facile intramolecular loss of methanol and cyclization to the xanthone.
