Check Digit Verification of cas no

The CAS Registry Mumber 49764-17-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,9,7,6 and 4 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 49764-17:
(7*4)+(6*9)+(5*7)+(4*6)+(3*4)+(2*1)+(1*7)=162
162 % 10 = 2
So 49764-17-2 is a valid CAS Registry Number.

CgPhen-DalPhos Enables the Nickel-CatalyzedO-Arylation of Tertiary Alcohols with (Hetero)Aryl Electrophiles

Morrison, Kathleen M.,McGuire, Ryan T.,Ferguson, Michael J.,Stradiotto, Mark

, p. 10878 - 10884 (2021/09/08)

While the Ni-catalyzed cross-coupling of primary or secondary aliphatic alcohols and (hetero)aryl electrophiles is known, related cross-couplings involving tertiary aliphatic alcohols, with a broad scope, are challenging. Herein we disclose that a NiIIprecatalyst featuring the ligand CgPhen-DalPhos is unusual in its ability to promote the C-O cross-coupling of tertiary aliphatic alcohols with (hetero)aryl halides (Cl, Br, and I) or phenol derivatives (OMs and OPiv). An exploration of substrate scope and competition experiments help to shed light on the capabilities and reactivity preferences of this catalyst system.
