Check Digit Verification of cas no

The CAS Registry Mumber 1215106-19-6 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,1,5,1,0 and 6 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1215106-19:
(9*1)+(8*2)+(7*1)+(6*5)+(5*1)+(4*0)+(3*6)+(2*1)+(1*9)=96
96 % 10 = 6
So 1215106-19-6 is a valid CAS Registry Number.

Selective Chemical Functionalization at N6-Methyladenosine Residues in DNA Enabled by Visible-Light-Mediated Photoredox Catalysis

Nappi, Manuel,Hofer, Alexandre,Balasubramanian, Shankar,Gaunt, Matthew J.

, p. 21484 - 21492 (2020)

Selective chemistry that modifies the structure of DNA and RNA is essential to understanding the role of epigenetic modifications. We report a visible-light-activated photocatalytic process that introduces a covalent modification at a C(sp3)-H bond in the methyl group of N6-methyl deoxyadenosine and N6-methyl adenosine, epigenetic modifications of emerging importance. A carefully orchestrated reaction combines reduction of a nitropyridine to form a nitrosopyridine spin-trapping reagent and an exquisitely selective tertiary amine-mediated hydrogen-atom abstraction at the N6-methyl group to form an α-amino radical. Cross-coupling of the putative α-amino radical with nitrosopyridine leads to a stable conjugate, installing a label at N6-methyl-adenosine. We show that N6-methyl deoxyadenosine-containing oligonucleotides can be enriched from complex mixtures, paving the way for applications to identify this modification in genomic DNA and RNA.
