Check Digit Verification of cas no

The CAS Registry Mumber 84170-99-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,4,1,7 and 0 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 84170-99:
(7*8)+(6*4)+(5*1)+(4*7)+(3*0)+(2*9)+(1*9)=140
140 % 10 = 0
So 84170-99-0 is a valid CAS Registry Number.

Enantioselective synthesis of α-tri- and α-tetrasubstituted allylsilanes by copper-catalyzed asymmetric allylic substitution of allyl phosphates with silylboronates

Takeda, Momotaro,Shintani, Ryo,Hayashi, Tamio

, p. 5007 - 5017 (2013/07/11)

A copper/N-heterocyclic carbene-catalyzed asymmetric allylic substitution of allyl phosphates with a silylboronate has been developed to give highly enantioenriched allylsilanes. High regioselectivity has been achieved by employing NaOH as the base, and this catalyst system is effective for both γ-mono- and disubstituted allyl phosphates.
