895918-10-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 895918-10-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,9,5,9,1 and 8 respectively; the second part has 2 digits, 1 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 895918-10:
(8*8)+(7*9)+(6*5)+(5*9)+(4*1)+(3*8)+(2*1)+(1*0)=232
232 % 10 = 2
So 895918-10-2 is a valid CAS Registry Number.

(±)-Diinsininone: made nature's way

Selenski, Carolyn,Pettus, Thomas R.R.

, p. 5298 - 5307 (2007/10/03)

We report the synthesis of diinsininone (33), the aglycone of (±)-diinsinin (2). Thereby, we complete the first construction of a proanthocyanidin (PA) type-A compound incorporating a [3.3.1]-bicyclic ketal as its characteristic core. Our strategy utilizes a coupling between a benzopyrilium salt and a flavanone that proves applicable to other PA type-A compounds. During this undertaking, treatment of naringenin (9) with 2-iodoxybenzoic acid (IBX) followed by reductive work-up affords eriodictyol (10). This reactivity mirrors that of catechol hydroxylase (F3H) found in the flavonoid pathway. Other interesting transformations include the formation of flavonoids through an ortho-quinone methide (o-QM) cycloaddition-oxidation sequence and regioselective β-glycosidations of several unprotected flavanones suggesting a likely synthesis of 2 from the aglycone 33.
