Check Digit Verification of cas no

The CAS Registry Mumber 945656-57-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,4,5,6,5 and 6 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 945656-57:
(8*9)+(7*4)+(6*5)+(5*6)+(4*5)+(3*6)+(2*5)+(1*7)=215
215 % 10 = 5
So 945656-57-5 is a valid CAS Registry Number.

Oxyanion steering and CH-π interactions as key elements in an N-heterocyclic carbene-catalyzed [4 + 2] cycloaddition

Allen, Scott E.,Mahatthananchai, Jessada,Bode, Jeffrey W.,Kozlowski, Marisa C.

supporting information; experimental part, p. 12098 - 12103 (2012/09/22)

The N-heterocyclic carbene catalyzed [4 + 2] cycloaddition has been shown to give γ,δ-unsaturated δ-lactones in excellent enantio- and diastereoselectivity. However, preliminary computational studies of the geometry of the intermediate enolate rendered am
