Check Digit Verification of cas no

The CAS Registry Mumber 669770-71-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,6,9,7,7 and 0 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 669770-71:
(8*6)+(7*6)+(6*9)+(5*7)+(4*7)+(3*0)+(2*7)+(1*1)=222
222 % 10 = 2
So 669770-71-2 is a valid CAS Registry Number.

Alkylation of Allyl/Alkenyl Sulfones by Deoxygenation of Alkoxyl Radicals

Han, Jia-Bin,Guo, Ao,Tang, Xiang-Ying

supporting information, p. 2989 - 2994 (2019/02/05)

A challenging deoxygenation of alkoxyl radicals from readily accessible alcohol derivatives was developed, affording facile synthesis of functionalized alkenes with good functional group tolerance under mild reaction conditions. Because alkoxyl radicals can easily undergo β-fragmentations or hydrogen abstractions, this new strategy for deoxygenation of alkoxyl radicals is highly valuable. Moreover, mechanistic studies revealed that the electron-neutral phosphine acts as the deoxygenation reagent.

Phosphinic acid-based MMP-13 inhibitors that spare MMP-1 and MMP-3

Reiter, Lawrence A.,Mitchell, Peter G.,Martinelli, Gary J.,Lopresti-Morrow, Lori L.,Yocum, Sue A.,Eskra, James D.

, p. 2331 - 2336 (2007/10/03)

Phosphinic acid-based inhibitors of MMP-13 have been investigated with the aim of identifying potent inhibitors with high selectivity versus MMP-1. Independent variation of the substituents on a P1′ phenethyl group and a P2 benzyl gr
