Check Digit Verification of cas no
The CAS Registry Mumber 82137-81-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,2,1,3 and 7 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 82137-81:
(7*8)+(6*2)+(5*1)+(4*3)+(3*7)+(2*8)+(1*1)=123
123 % 10 = 3
So 82137-81-3 is a valid CAS Registry Number.

-
, (2020/12/14)
The invention discloses a method for preparing black reversible thermochromic dyes. The black reversible thermochromic dye uses a compound (II) as a raw material. The structure of the compound is shown as the formula (II) which is described in the specification. In the formula (II), R1 is C1-C10 alkane; and R2 is C1-C10 alkane. The compound shown as the formula (II) reacts with various alkylationreagents to prepare corresponding dialkylated substances, and a hydrolysis reaction is conducted on the dialkylated substances to obtain target compounds (I). According to the invention, the compoundshown as the formula (II) is used as a core fragment substance and reacts with different alkylation reagents, so a series of the black reversible thermochromic dyes can be quickly prepared; synthesisefficiency is high; and the industrial production of a series of the products is convenient to realize.
