136197-46-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 136197-46-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,6,1,9 and 7 respectively; the second part has 2 digits, 4 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 136197-46:
(8*1)+(7*3)+(6*6)+(5*1)+(4*9)+(3*7)+(2*4)+(1*6)=141
141 % 10 = 1
So 136197-46-1 is a valid CAS Registry Number.

1,3-DIOXANES FROM 1,2-NAPHTHALENONES
Chumachenko, N. V.,Kolesnikov, V. T.,Novikov, V. P.
, p. 728 - 731 (2007/10/02)
Condensed 1,3-dioxanes were obtained by the treatment of 1,2-naphthalenones with hydrogen halides in acetone or propionaldehyde.In stringly acidic media the reaction was reversible.The dioxane derivatives were used as intermediate products during halogena
