1428940-92-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1428940-92-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,2,8,9,4 and 0 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1428940-92:
(9*1)+(8*4)+(7*2)+(6*8)+(5*9)+(4*4)+(3*0)+(2*9)+(1*2)=184
184 % 10 = 4
So 1428940-92-4 is a valid CAS Registry Number.

General synthetic approach to functionalized dihydrooxepines
Nicolaou,Yu, Ruocheng,Shi, Lei,Cai, Quan,Lu, Min,Heretsch, Philipp
, p. 1994 - 1997 (2013/06/04)
A three-step sequence to access functionalized 4,5-dihydrooxepines from cyclohexenones has been developed. This approach features a regioselective Baeyer-Villiger oxidation and subsequent functionalization via the corresponding enol phosphate intermediate.
