Check Digit Verification of cas no

The CAS Registry Mumber 124525-54-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,4,5,2 and 5 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 124525-54:
(8*1)+(7*2)+(6*4)+(5*5)+(4*2)+(3*5)+(2*5)+(1*4)=108
108 % 10 = 8
So 124525-54-8 is a valid CAS Registry Number.

Sodium tetraborate/benzyltriethylammonium chloride-mediated synthesis of substituted cinnamic acids from aromatic aldehydes and aliphatic carboxylic acids

Nechifor, Marioara,Chiriac, Constantin I.,Tanasa, Fulga

, p. 161 - 164 (2014/04/03)

A simple, efficient, and cost-effective method has been developed for the synthesis of some cinnamic acid derivatives in moderate to high yields (63-86%) by a one-pot condensation reaction of benzaldehyde and aliphatic carboxylic acids in the presence of sodium tetraborate and benzyltriethylammonium chloride, and N-methyl-pyrrolidinone as solvent. The reaction requires high temperatures (reflux at 180-190°C) and strong basic conditions, which have been generated by pyridine and 4-dimethylaminopyridine added to the reaction medium.

A novel direct boron-mediated synthesis of cinnamic acids from aromatic aldehydes and aliphatic carboxylic acids

Chiriac, Constantin I.,Tanasa, Fulga,Nechifor, Marioara

experimental part, p. 987 - 991 (2011/06/21)

Cinnamic acids have been prepared in 64-85% yields by a new direct synthesis from aromatic aldehydes and aliphatic carboxylic acids in the presence of anhydrous sodium tetraborate and lithium chloride, bases as pyridine (Py) and 4-dimethylaminopyridine (DMAP), and N-methyl-2-pyrolidinone (NMP) as solvent, at reflux (180-190°C), for 8-12 hours. Without sodium tetraborate-lithium chloride this reaction is not possible.
