Check Digit Verification of cas no

The CAS Registry Mumber 854624-37-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,5,4,6,2 and 4 respectively; the second part has 2 digits, 3 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 854624-37:
(8*8)+(7*5)+(6*4)+(5*6)+(4*2)+(3*4)+(2*3)+(1*7)=186
186 % 10 = 6
So 854624-37-6 is a valid CAS Registry Number.

Pd(OAc)2-catalyzed dinitration reaction of aromatic amines

Feng, Yi-Si,Mao, Long,Bu, Xiao-Song,Dai, Jian-Jun,Xu, Hua-Jian

, p. 3827 - 3832 (2015)

Taking advantage of Pd(OAc)2-catalyzed dinitration reactions with Bi(NO3)3·5H2O in trifluoroethanol (TFE) and trifluoroacetic acid (TFA), we have developed an efficient and practical method for the synthesis of secondary dinitro-aromatic amines. The products could be applied to the preparation of 5-amine-N-methyl-benzimidazolone, the azo-dyes, economic advantages. The method has also been expanded to the dinitration reaction of some tertiary aromatic amines.
