Check Digit Verification of cas no

The CAS Registry Mumber 65894-26-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,5,8,9 and 4 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 65894-26:
(7*6)+(6*5)+(5*8)+(4*9)+(3*4)+(2*2)+(1*6)=170
170 % 10 = 0
So 65894-26-0 is a valid CAS Registry Number.

Method for catalyzing aldol self-condensation reaction of low-carbon aldehyde by acid alkali double-function ionic liquid

-

Paragraph 0042-0044, (2018/03/01)

The invention relates to a method for catalyzing aldol self-condensation reaction of low-carbon aldehyde by acid alkali double-function ionic liquid. The method comprises the following steps: adding low-carbon aldehyde and an acid alkali double-function ionic liquid catalyst into a high-pressure kettle, reacting at 60 to 150 DEG C for 1 to 12 hours, and performing hydroxyaldehyde self-condensationreaction on the low-carbon aldehyde to obtain long-chain unsaturated aldehyde, wherein the acid alkali double-function ionic liquid is the acid alkali double-function ionic liquid with cation and anion containing acid and alkali groups correspondingly, or the novel acid alkali double-function ionic liquid with cation containing acid and alkali groups. The method is applied to aldol self-condensation reaction of n-butanal and n-pentanal and is mild in reaction condition, high in catalytic activity and high in selectivity; and the acid alkali double-function ionic liquid catalyst can be reused.
