Check Digit Verification of cas no

The CAS Registry Mumber 31539-26-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,1,5,3 and 9 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 31539-26:
(7*3)+(6*1)+(5*5)+(4*3)+(3*9)+(2*2)+(1*6)=101
101 % 10 = 1
So 31539-26-1 is a valid CAS Registry Number.

ASYMMETRIC BIS(1,2-DIARYLAMINO)BENZENE AND METHOD FOR PRODUCING THE SAME

-

Paragraph 0067-0069, (2017/12/06)

PROBLEM TO BE SOLVED: To provide asymmetric bis(1,2-diarylamino)benzene utilizable as an organic EL element material, a method for producing the same, and orthophenylene diamine as an intermediate body useful for producing the bis(1,2-diarylamino)benzene. SOLUTION: Provided is a method for producing asymmetric bis(1,2-diarylamino)benzene where asymmetric bis(1,2-diarylamino)benzene, diarylamine and a Grignard reagent are reacted to obtain magnesium diarylamide, thereafter, the magnesium diarylamide is reacted with a transition metal catalyst and an oxidizer to obtain orthophenylene diamine (2), and the same is reacted with a halogen compound in the presence of a transition metal catalyst and a base. Further, orthophenylene diamine as an intermediate body useful for producing the bis(1,2-diarylamino)benzene is used. SELECTED DRAWING: None COPYRIGHT: (C)2017,JPOandINPIT
