Check Digit Verification of cas no

The CAS Registry Mumber 1620650-85-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,2,0,6,5 and 0 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1620650-85:
(9*1)+(8*6)+(7*2)+(6*0)+(5*6)+(4*5)+(3*0)+(2*8)+(1*5)=142
142 % 10 = 2
So 1620650-85-2 is a valid CAS Registry Number.

Catalytic enantioselective inverse electron demand hetero-diels-alder reaction with allylsilanes

Matsumura, Yuki,Suzuki, Takahiro,Sakakura, Akira,Ishihara, Kazuaki

, p. 6131 - 6134 (2014/06/23)

The first diastereo- and enantioselective inverse electron demand hetero-Diels-Alder reaction of β,γ-unsaturated α-ketoesters with allylsilanes is described. Chiral copper(II) catalysts successfully activate the β,γ-unsaturated α-ketoesters and promote the reaction with allylsilanes with excellent enantioselectivities. This process represents a new entry to chiral oxanes.
