106185-66-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 106185-66-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,6,1,8 and 5 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 106185-66:
(8*1)+(7*0)+(6*6)+(5*1)+(4*8)+(3*5)+(2*6)+(1*6)=114
114 % 10 = 4
So 106185-66-4 is a valid CAS Registry Number.

Direct 4-Alkylation of 1,3-Cyclohexanediones via Dianionic Species
Berry, Nicola M.,Darey, Mark C. P.,Harwood, Laurence M.
, p. 476 - 480 (2007/10/02)
1,3-Cyclohexanediones are directly alkylated at the 4 position via dianionic species generated at -78 deg C using lithium diisopropylamine/hexamethylphosphoric triamide.Acetylation of the reaction products at room temperature yields the 3-acetoxy-6-alkylc
