14729-11-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 14729-11-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,4,7,2 and 9 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 14729-11:
(7*1)+(6*4)+(5*7)+(4*2)+(3*9)+(2*1)+(1*1)=104
104 % 10 = 4
So 14729-11-4 is a valid CAS Registry Number.

Synthesis of ptaeroxylin (desoxykarenin): An unusual chromone from the sneezewood tree Ptaeroxylon obliquum

Muscarella, Marina,Kimber, Marc C.,Moody, Christopher J.

, p. 2101 - 2102 (2008)

The first synthesis of the oxepinochromone ptaeroxylin (also known as desoxykarenin) isolated from the sneezewood tree is described, in which the key steps are a Claisen rearrangement and a ring-closing metathesis to form the seven-membered oxygen heterocyclic ring. Georg Thieme Verlag Stuttgart. (Table Presented).
