Check Digit Verification of cas no
The CAS Registry Mumber 6303-60-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,3,0 and 3 respectively; the second part has 2 digits, 6 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 6303-60:
(6*6)+(5*3)+(4*0)+(3*3)+(2*6)+(1*0)=72
72 % 10 = 2
So 6303-60-2 is a valid CAS Registry Number.

An aqueous Heck reaction carried out under ultrasonic irradiation at the ambient temperature (25 °C) has been shown in this study to afford high yields of corresponding products. It was found that as a catalyst for the reaction palladium forms nanoparticles in-situ, characterized by transmission electron microscopy (TEM) and X-ray powder diffraction (XRD) analyses, and can be recycled. Furthermore, the Heck reaction under such mild and environmentally friendly conditions offers excellent regioselectivity of para-over ortho-substitution in phenyl iodides especially with electron-donating groups.
