The CAS Registry Mumber 228249-84-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,8,2,4 and 9 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 228249-84:
(8*2)+(7*2)+(6*8)+(5*2)+(4*4)+(3*9)+(2*8)+(1*4)=151
151 % 10 = 1
So 228249-84-1 is a valid CAS Registry Number.

Total, asymmetric synthesis of ethyl D-ido-4-heptulosuronate derivatives starting from diethyl 4-oxopimelate

Lemaire-Audoire, Sandrine,Vogel, Pierre

, p. 1283 - 1293 (1999)

Bromination of diethyl 4-oxopimelate, followed by double elimination of HBr and ketalization provided diethyl (E,E)-4,4-(ethylidenedioxy)hepta-2,5- dienedioate 4. Sharpless asymmetric dihydroxylation of 4 produced diethyl (2S,3S)-4,4-(ethylidenedioxy)-2,3
