181931-41-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 181931-41-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,1,9,3 and 1 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 181931-41:
(8*1)+(7*8)+(6*1)+(5*9)+(4*3)+(3*1)+(2*4)+(1*1)=139
139 % 10 = 9
So 181931-41-9 is a valid CAS Registry Number.

Intermolecular Phosphite-Mediated Radical Desulfurative Alkene Alkylation Using Thiols

Lopp, John M.,Schmidt, Valerie A.

, p. 8031 - 8036 (2019/10/19)

We report herein the development of a S atom transfer process using triethyl phosphite as the S atom acceptor that allows thiols to serve as precursors of C-centered radicals. A range of functionalized and electronically unbiased alkenes including those containing common heteroatom-based functional groups readily participate in this reductive coupling. This process is driven by the exchange of relatively weak S-H and C-S bonds of aliphatic thiols for C-H, C-C, and S-P bonds of the products formed.
