Check Digit Verification of cas no
The CAS Registry Mumber 13674-84-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,3,6,7 and 4 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 13674-84:
(7*1)+(6*3)+(5*6)+(4*7)+(3*4)+(2*8)+(1*4)=115
115 % 10 = 5
So 13674-84-5 is a valid CAS Registry Number.

Paragraph 0031-0038, (2017/08/25)
The invention relates to a preparation method of tri(2-chloroisopropyl)phosphate (TCPP). The TCPP is prepared by reacting dehydrated epoxypropane and phosphorus oxychloride. The invention particularly relates to a preparation method of TCPP with low TCPP ether impurity content and high product yield. The method comprises the following steps: before adding the epoxypropane to react, adding a dehydrating agent into the epoxypropane or passing the epoxypropane through a dehydrating-agent-filled dehydration tower to perform deep dehydration on the epoxypropane until the water content in the epoxypropane is less than 100 ppm, and reacting with the phosphorus oxychloride to obtain the TCPP. The TCPP ether content in the TCPP product is less than 1000 ppm. Compared with the TCPP obtained in the prior art, the method greatly lowers the TCPP ether content in the product and enhances the product yield.
