Check Digit Verification of cas no

The CAS Registry Mumber 1220779-38-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,2,0,7,7 and 9 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1220779-38:
(9*1)+(8*2)+(7*2)+(6*0)+(5*7)+(4*7)+(3*9)+(2*3)+(1*8)=143
143 % 10 = 3
So 1220779-38-3 is a valid CAS Registry Number.

Concise total syntheses of aspalathin and nothofagin

Yepremyan, Akop,Salehani, Baback,Minehan, Thomas G.

, p. 1580 - 1583 (2010)

Chemical Fig. Reprentation Syntheses of the C-glycosyl flavone natural products aspalathin and nothofagin have been accomplished in eight steps from tribenzyl glucal, tribenzylphloroglucinol, and either 4-(benzyloxy) phenylacetylene or 3,4-bis(benzyloxy)phenylacetylene. The key step of the syntheses involves a highly stereoselective Lewis acid promoted coupling of 1,2-di-o-acyl-3,4,6-tribenzylglucose with tribenzylphloroglucinol, which gives rise to the corresponding β-C-aryl glycoside in 30-65% yields.
