Check Digit Verification of cas no

The CAS Registry Mumber 213328-56-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,3,3,2 and 8 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 213328-56:
(8*2)+(7*1)+(6*3)+(5*3)+(4*2)+(3*8)+(2*5)+(1*6)=104
104 % 10 = 4
So 213328-56-4 is a valid CAS Registry Number.

Total synthesis of uvaricin

Yazbak, Ahmad,Sinha, Subhash C.,Keinan, Ehud

, p. 5863 - 5868 (2007/10/03)

The first total synthesis of naturally occurring (+)-uvaricin was achieved using three consecutive Sharpless asymmetric dihydroxylation (AD) reactions to place the necessary oxygen functions on a 'naked' carbon skeleton in a regio- and enantioselectively controlled manner. The appropriate bis-THF ring system was constructed using a Williamson type etherification reaction on a functionalized bis-mesylate intermediate.
