Check Digit Verification of cas no
The CAS Registry Mumber 622-15-1 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 6,2 and 2 respectively; the second part has 2 digits, 1 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 622-15:
(5*6)+(4*2)+(3*2)+(2*1)+(1*5)=51
51 % 10 = 1
So 622-15-1 is a valid CAS Registry Number.

Application of chlorodifluoromethane as C1 source for synthesis of amidine compounds
-
Paragraph 0040-0041, (2019/09/17)
The invention discloses an application of chlorodifluoromethane as a C1 source for synthesis of amidine compounds. Chlorodifluoromethane can be subjected to quadrupole bond cracking under a mild condition, and valuable amidine compounds can be obtained. Water and a solvent are added in the presence of chlorodifluoromethane, the chlorodifluoromethane can be efficiently cracked into a C1 synthon, and synthesis of the amidine compounds can be realized. The synthesis method uses no transition metal, has the characteristic of being environmentally friendly, is simple to operate and can obtain the amidine compounds by one step.
