81077-60-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 81077-60-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,1,0,7 and 7 respectively; the second part has 2 digits, 6 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 81077-60:
(7*8)+(6*1)+(5*0)+(4*7)+(3*7)+(2*6)+(1*0)=123
123 % 10 = 3
So 81077-60-3 is a valid CAS Registry Number.

Electrophilic Methylthiomethylation of Enol Ethers and Activated Aromatic Compounds. Application of the Former Reaction to the Synthesis of the Macrocycle, 3,3,7,7,11,11,15,15-Octamethyl-1,9-dithia-5,13-diazacyclohexadecane

McCrindle, Robert,McAlees, Alan J.,Stephenson, Donald K.

, p. 3070 - 3073 (1981)

Enol ethers of dialkylacetaldehydes, either as such, or generated in situ from the corresponding acetals, undergo ready methylthiomethylation when heated with dimethyl sulphoxide-acetic anhydride (or methylthiomethyl acetate) in the presence of boron trifluoride-diethyl ether.These same reagent combinations can be used to methylthiomethylate certain activated aromatic compounds.The synthetic utility of the former reaction is demonstrated in the synthesis of 2,2,6,6-dimethyl-4-thiaheptanedial (4) which has been converted into 3,3,7,7,11,11,15,15-octamethyl-1,9-dithia-5,13-diazacyclohexadecane (7).
