125639-32-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 125639-32-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,5,6,3 and 9 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 125639-32:
(8*1)+(7*2)+(6*5)+(5*6)+(4*3)+(3*9)+(2*3)+(1*2)=129
129 % 10 = 9
So 125639-32-9 is a valid CAS Registry Number.

Synthesis of the papulacandin C-arylglucosyl spiroketal nucleus
Rosenblum, Stuart B.,Bihovsky, Ron
, p. 2746 - 2748 (2007/10/02)
The enantiomerically pure tricyclic C-arylglucosyl spiroketal nucleus of papulacandin has been synthesized by reaction of an appropriately protected gluconolactone 4 with a metalated derivative of 5-(hydroxymethyl)resorcinol (5). In model studies, alkylli
