805319-52-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 805319-52-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,0,5,3,1 and 9 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 805319-52:
(8*8)+(7*0)+(6*5)+(5*3)+(4*1)+(3*9)+(2*5)+(1*2)=152
152 % 10 = 2
So 805319-52-2 is a valid CAS Registry Number.

Stoichiometric and catalytic reductive aldol cyclizations of alkynediones induced by Stryker's reagent
Chiu, Pauline,Leung, Sze Kar
, p. 2308 - 2309 (2007/10/03)
Conjugate reduction of alkynones by stoichiometric [(Ph3P)CuH] 6 or catalytic [(Ph3P)CuH]6 and polymethylhydrosiloxane proceeds to cyclization by an aldol reaction with tethered ketones to generate β-hydroxyenon
