2917-78-4 Usage
General Description
Dimethyl isopropylmalonate, also known as Isopropyl dimethylmalonate, is an organic compound derived from malonic acid used primarily in chemical synthesis operations. It's a colorless liquid with a mild, pleasant odor. The compound plays a significant role in the pharmaceutical industry where it contributes to drug manufacturing processes. Given its chemical nature, specific safety measures need to be observed when handling Dimethyl isopropylmalonate. These include avoiding contact with the skin or eyes, inhalation, or ingestion, as it can cause discomfort and possible health hazards. This chemical is non-combustible but can decompose to hazardous products when exposed to heat.
Check Digit Verification of cas no
The CAS Registry Mumber 2917-78-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,9,1 and 7 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 2917-78:
(6*2)+(5*9)+(4*1)+(3*7)+(2*7)+(1*8)=104
104 % 10 = 4
So 2917-78-4 is a valid CAS Registry Number.

Hydrogenolysis of Small Cycloalkanes, XVII. - Catalytic Hydrogenation of Dimethyl Bicyclobutane-2,2-dicarboxylate

, p. 443 - 444 (2007/10/02)
Catalytic hydrogenation of the title compound 1 yields 92-95percent of ethyl methyl malonate (2), 3-5percent of n-propyl malonate (3), 2-3percent of dimethyl 2-methyl-1,1-cyclopropanedicarboxylate (4), and no 1,1-cyclobutanedicarboxylate 5, the formation of which, however, can be induced with a poisoned catalyst.
