Check Digit Verification of cas no
The CAS Registry Mumber 15707-23-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,5,7,0 and 7 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 15707-23:
(7*1)+(6*5)+(5*7)+(4*0)+(3*7)+(2*2)+(1*3)=100
100 % 10 = 0
So 15707-23-0 is a valid CAS Registry Number.

Paragraph 0024; 0029; 0035; 0041; 0049; 0053, (2018/04/01)
The invention discloses an efficient synthesis method of 2-ethyl-3-methylpyrazine. The method comprises specific steps as follows: 2,3-pentanedione is prepared from lactic acid as a raw material, a porous carrier is prepared from raw materials including diammonium hydrogen phosphate and barium nitrate, caesium supported on the carrier is taken as a catalyst, and the conversion rate of lactic acidis effectively increased; then, prepared 2,3-pentanedione and ethylenediamine are taken as raw materials and are sequentially subjected to dehydration condensation and dehydrogenation reactions, and 2-ethyl-3-methylpyrazine is prepared. The synthesis method is simple, low in cost and high in product yield.
