Check Digit Verification of cas no
The CAS Registry Mumber 22667-21-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,2,6,6 and 7 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 22667-21:
(7*2)+(6*2)+(5*6)+(4*6)+(3*7)+(2*2)+(1*1)=106
106 % 10 = 6
So 22667-21-6 is a valid CAS Registry Number.

Hydrolysis of gem-dibromomethylarenes bearing carboxylate or boronate group to corresponding aldehydes without affecting the ester group was successfully accomplished in high yields by subjecting them to refluxing pyridine. Both aromatic and heteroaromatic substrates gave the corresponding aldehydes in good yields. This method was efficiently adapted for the large scale synthesis of 2d and 2f.
