Check Digit Verification of cas no
The CAS Registry Mumber 319432-22-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,1,9,4,3 and 2 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 319432-22:
(8*3)+(7*1)+(6*9)+(5*4)+(4*3)+(3*2)+(2*2)+(1*2)=129
129 % 10 = 9
So 319432-22-9 is a valid CAS Registry Number.

A regioselective functionalization of the pyrazolo[1,5-a]pyridine scaffold using Mg- and Zn-TMP bases (TMP = 2,2,6,6-tetramethylpiperidyl) in the presence or absence of BF3·OEt2 is described. Also, various functionalized pyrazolo[1,5-a]pyridines bearing an ester function (and an NHBoc or ethyl group) are magnesiated and functionalized, leading to polysubstituted heterocycles. Additionally, a sulfoxide directed ortho-metalation, followed by the transition-metal-free amination of a pyrazolo[1,5-a]pyridine sulfoxide, using a magnesium amide, is reported.
