86631-39-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 86631-39-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,6,6,3 and 1 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 86631-39:
(7*8)+(6*6)+(5*6)+(4*3)+(3*1)+(2*3)+(1*9)=152
152 % 10 = 2
So 86631-39-2 is a valid CAS Registry Number.

METHOD FOR PRODUCING 4- TO 6-MER OF CATECHIN AND EPICATECHIN

-

Paragraph 0059; 0060; 0065; 0066, (2016/10/08)

PROBLEM TO BE SOLVED: To provide a method for producing a 4- to 6-mer of catechin or epicatechin optical selectively and efficiently. SOLUTION: The 4- to 6-mer of catechin can be produced efficiently by using a 3- to 5-mer of catechin as a nucleophile, and a catechin monomer as an electrophile, and by reacting them in the presence of silver triflate (Ag(CF3SO3)). Furthermore, the 4- to 6-mer of epicatechin can be produced efficiently by using a 2-mer of epicatechin as a nucleophile, and a 2- to 4-mer of epicatechin monomer as an electrophile, and reacting them in the presence of zinc triflate (Zn(CF3SO3)2).
