Check Digit Verification of cas no
The CAS Registry Mumber 30166-77-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,0,1,6 and 6 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 30166-77:
(7*3)+(6*0)+(5*1)+(4*6)+(3*6)+(2*7)+(1*7)=89
89 % 10 = 9
So 30166-77-9 is a valid CAS Registry Number.

Herein we report a protocol for the direct visible-light-mediated alkenylation of alkyl boronic acids at room temperature without an external Lewis base as an activator, and we propose a mechanism involving benzenesulfinate activation of the alkyl boronic acids. The protocol permits the efficient functionalization of a broad range of cyclic and acyclic primary and secondary alkyl boronic acids with various alkenyl sulfones. We demonstrated its utility by preparing or functionalizing several pharmaceuticals and natural products.
