Check Digit Verification of cas no
The CAS Registry Mumber 6358-31-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,3,5 and 8 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 6358-31:
(6*6)+(5*3)+(4*5)+(3*8)+(2*3)+(1*1)=102
102 % 10 = 2
So 6358-31-2 is a valid CAS Registry Number.

Production process and system for insoluble azo pigments
-
Page/Page column 8; 10, (2008/06/13)
An insoluble azo pigment is produced by ejecting a diazo solution and a grounding solution continuously into an ejector such that within the ejector, the diazo solution and grounding solution are mixed with each other and are subjected to a coupling reaction. A production system for the insoluble azo pigment includes the following units (1) to (4): (1) a first feed tank (2) for a first fluid selected from the diazo solution or grounding solution, a first flow path (a) for feeding the first fluid to nozzles of an ejector (1), and a pump (d) for feeding the first fluid through the first flow path; (2) the ejector (1) provided with the nozzles, a suction chamber, a diffuser, and a temperature control device (g); (3) a second feed tank (3) for a second fluid, a second flow path (b) for guiding the second fluid into the suction chamber, and a flow control device (e) for controlling a flow rate of the second fluid through the second flowpath (b); and (4) a heat treatment tank (5) for subjecting to heat treatment a suspension of the insoluble azo pigment formed by a reaction between the first fluid and the second fluid, and a third flow path (a′) for guiding the suspension from the diffuser to the heat treatment tank.
