Check Digit Verification of cas no

The CAS Registry Mumber 1373280-11-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,7,3,2,8 and 0 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1373280-11:
(9*1)+(8*3)+(7*7)+(6*3)+(5*2)+(4*8)+(3*0)+(2*1)+(1*1)=145
145 % 10 = 5
So 1373280-11-5 is a valid CAS Registry Number.

Ultrasound-assisted aza-Michael reaction in water: A green procedure

Bandyopadhyay, Debasish,Mukherjee, Sanghamitra,Turrubiartes, Luis C.,Banik, Bimal K.

, p. 969 - 973 (2012)

The conjugate addition of amines to conjugated alkenes (commonly known as aza-Michael reaction) constitutes a key step for the synthesis of various complex natural products, antibiotics, α-amino alcohols and chiral auxiliaries. Ultrasound-induced addition of several amines to α, β-unsaturated ketones, esters and nitriles has been carried out very efficiently in water as well as under solvent-free conditions. No catalysts or solid supports have been used in this method. Remarkable enhancement of reaction rate has been observed in water under ultrasound-induced method. This environmentally benign procedure has provided clean formation of the products with better selectivity.
