Check Digit Verification of cas no

The CAS Registry Mumber 476452-73-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,7,6,4,5 and 2 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 476452-73:
(8*4)+(7*7)+(6*6)+(5*4)+(4*5)+(3*2)+(2*7)+(1*3)=180
180 % 10 = 0
So 476452-73-0 is a valid CAS Registry Number.

Practical synthesis of β-carbonyl phenyltetrazolesulfones and investigations of their reactivities in organocatalysis

Zweifel, Theo,Nielsen, Martin,Overgaard, Jacob,Jacobsen, Christian Borch,Jorgensen, Karl Anker

supporting information; experimental part, p. 47 - 52 (2011/03/18)

A practical synthesis of β-carbonyl phenyltetrazolesulfones, useful for a series of enantioselective reactions, is shown. Aryl, alkyl and ester carbonyl compounds all proved to be efficiently synthesised, leading to products in up to >99% yield over two s

Ruthenium-catalyzed alkene-alkyne coupling: Synthesis of the proposed structure of amphidinolide A

Trost, Barry M.,Chisholm, John D.,Wrobleski, Stephen T.,Jung, Michael

, p. 12420 - 12421 (2007/10/03)

The ruthenium-catalyzed alkene-alkyne coupling provides a powerful method for the synthesis of 1,4 dienes and a way to simplify synthetic strategy. The latter potential is explored in the context of a synthesis of the assigned structure of amphidinolide A
