Check Digit Verification of cas no

The CAS Registry Mumber 19408-97-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,9,4,0 and 8 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 19408-97:
(7*1)+(6*9)+(5*4)+(4*0)+(3*8)+(2*9)+(1*7)=130
130 % 10 = 0
So 19408-97-0 is a valid CAS Registry Number.

Synthesis and plant growth retardant activity of bis-quaternary salts of ammonia from phenols

Sharma,Bala, Madhu

, p. 975 - 977 (2007/10/03)

Trialkylamines 3-(2-benzylphenoxy)-l-N,N-diethylaminpropan-2-ol (4a), 3-(4-benzylphenoxy)-l-N,N-diethylaminpropan-2-ol (4b), 3-(5-n-hutoxyphcnoxy)-l- N,N-diethylaminpropan-2-ol (4c) and 4,4'-bis(3-N,N-diethylamin-2- hydroxypropanoxy)biphenyl (9) were prepared from respective phenols and converted into corresponding bis-quaternary salts by reacting (4a-c) with malonyl chloride and (9) with ethyl bromide. These salts were tested for biological activity on germination, seedling growth and adventitious root formation on hypocotyl cuttings of Vigina radiata (SML-668). The results of biological studies of different compounds show that these salts do not inhibit seed germination and rather promotory in increasing shoot elongation if used from 10-50 μg/ml. However, all those compounds showed inhibitory action at higher concentration i.e. 100 μg/ml.
