Check Digit Verification of cas no

The CAS Registry Mumber 1096960-88-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,9,6,9,6 and 0 respectively; the second part has 2 digits, 8 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1096960-88:
(9*1)+(8*0)+(7*9)+(6*6)+(5*9)+(4*6)+(3*0)+(2*8)+(1*8)=201
201 % 10 = 1
So 1096960-88-1 is a valid CAS Registry Number.

Method for preparing meconazole intermediate

-

Paragraph 0057-0059; 0072-0074; 0079-0081, (2021/11/21)

The invention relates to a preparation technology of a bactericide, namely, meconazole, and discloses a method for preparing a compound shown as a formula (I), which comprises the following steps: (1) in the presence of organic alkali, contacting a compound shown as a formula (II) with a compound shown as a formula (III) for a condensation reaction; and (2) sequentially carrying out hydrolysis reaction I and decarboxylation reaction on a product obtained after the condensation reaction to obtain the compound shown in the formula (I). In the process for preparing the compound as shown in the formula (I), a Grignard reagent is not used, the cost of raw materials is effectively reduced, three wastes generated in the process are reduced, meanwhile, the total yield of the reaction is high, and the method is suitable for industrial mass production. .
