1428331-78-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1428331-78-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,2,8,3,3 and 1 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1428331-78:
(9*1)+(8*4)+(7*2)+(6*8)+(5*3)+(4*3)+(3*1)+(2*7)+(1*8)=155
155 % 10 = 5
So 1428331-78-5 is a valid CAS Registry Number.

A new oxa-Michael reaction and a gold-catalysed cyclisation en route to C-glycosides
Redon, Sébastien,Wierzbicki, Michel,Prunet, Jo?lle
, p. 2089 - 2092 (2013/04/24)
Two new syntheses of benzyl C-glycosides have been developed. The first one involves an unprecedented oxa-Michael cyclisation and the second one relies on an efficient gold-catalysed ring-closure.
