907997-09-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 907997-09-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,0,7,9,9 and 7 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 907997-09:
(8*9)+(7*0)+(6*7)+(5*9)+(4*9)+(3*7)+(2*0)+(1*9)=225
225 % 10 = 5
So 907997-09-5 is a valid CAS Registry Number.

Synthesis of 3-aryl-substituted tetrahydropyran-4-ones and tetrahydrothiopyran-4-ones

Rosiak, Anna,Christoffers, Jens

, p. 1434 - 1436 (2006)

A series of tetrahydropyran-4-one and tetrahydrothiopyran-4-one derivatives with 3-aryl or 3,6-diaryl substituents were prepared by double conjugate addition of water or H2S to divinyl ketones. These starting materials were accessed in two step
