Check Digit Verification of cas no

The CAS Registry Mumber 17042-18-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,7,0,4 and 2 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 17042-18:
(7*1)+(6*7)+(5*0)+(4*4)+(3*2)+(2*1)+(1*8)=81
81 % 10 = 1
So 17042-18-1 is a valid CAS Registry Number.

Stereoselective Formation of cis-2,3-Dimethylcyclopropanone Hemiacetals from 2-Halo-3-pentanones. - Cycloadditions with Conjugated Diene Systems

Foehlisch, Baldur,Gehrlach, Eberhard,Stezowski, John J.,Kollat, Petra,Martin, Eveline,Gottstein, Wolfgang

, p. 1661 - 1682 (2007/10/02)

2-Chloro- and 2-bromo-3-pentanone (1,2) react in methanol, ethanol, and 2-propanol with the corresponding sodium alkoxides in a highly stereoselective manner to provide the hemiacetals of cis-2,3-dimethylcyclopropanone (4aα-4cα).The benzoate of 4aα was characterized by an X-ray crystal structure determination. cis-2,3-Dimethylcyclopropanone can be trapped by an aldol type addition with dimethyl malonate.It undergoes a disrotatory retro-electrocyclic ring opening to form a W-configured allylium-2-olate (oxyallyl) 10 which combines with isoprene, (E)-1,3-pentadiene,furan, and 2-methylfuran in highly stereoselective cycloadditions.With methanol and 2,2,2-trifluoroethanol, the 2-alkoxy-3-pentanones are formed.N-Methylpyrrol is oxoalkylated at the 2-position.
