Check Digit Verification of cas no

The CAS Registry Mumber 227959-44-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,7,9,5 and 9 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 227959-44:
(8*2)+(7*2)+(6*7)+(5*9)+(4*5)+(3*9)+(2*4)+(1*4)=176
176 % 10 = 6
So 227959-44-6 is a valid CAS Registry Number.

Piperidinyl-3-phosphinic acids as novel uptake inhibitors of the neurotransmitter γ-aminobutyric acid (GABA)

Kehler, Jan,Stensbol, Tine B.,Krogsgaard-Larsen, Povl

, p. 811 - 814 (2007/10/03)

Piperidinyl-3-phosphinic acid 2, piperidinyl-3-methylphosphinic acid 3 and N-(4,4-diphenyl-3-butenyl)-piperidinyl-3-phosphinic acid 4 have been synthesized as bioisosteres of the corresponding amino carboxylic acids, which are potent and specific GABA-uptake inhibitors. The novel amino phosphinic acids were tested for their GABA-uptake inhibitory activity and 2 and 4 were identified as the first phosphinic acid based GABA-uptake inhibitors. The methylphosphinic acid 3 was found to be inactive.
