Check Digit Verification of cas no
The CAS Registry Mumber 27132-23-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,7,1,3 and 2 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 27132-23:
(7*2)+(6*7)+(5*1)+(4*3)+(3*2)+(2*2)+(1*3)=86
86 % 10 = 6
So 27132-23-6 is a valid CAS Registry Number.

Method for preparing diethyl malonate
-
Paragraph 0014, (2020/06/02)
The invention relates to a novel method for preparing diethyl malonate, comprisign the following steps: using malonate as a raw material, sodium hydride as a catalyst and diethyl sulfate as an ethylation reagent, stirring at 70-100 DEG C to react for 3-5 hours, and carrying out after-treatment on the reaction solution after the reaction is finished. The method is low in cost, easy in reaction operation and high in yield.
