75987-85-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 75987-85-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,5,9,8 and 7 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 75987-85:
(7*7)+(6*5)+(5*9)+(4*8)+(3*7)+(2*8)+(1*5)=198
198 % 10 = 8
So 75987-85-8 is a valid CAS Registry Number.

Thiomethylation of ketones by sodium sulphide and formaldehyde

Ulendeyeva,Bayeva,Lyapina,Shmakov,Galkin

, p. 177 - 186 (2007/10/03)

The thiomethylation of propanol, butanol, cyclohexanone and acetophenone with a mixture of formaldehyde and sodium sulphide proceeds at 20°C and normal pressure for 1-7 hr. It has been established that the reactivity of ketones increases in the order butanone-cyclohexanone-propanone-acetophenone. The conversion of sodium sulphide depends on its initial concentration, the nature of the ketone, and the presence in the reaction medium of sodium hydroxide and ethyl alcohol. It has been shown that the reaction proceeds with the preferential formation of keto- and diketosulphides.
