Check Digit Verification of cas no

The CAS Registry Mumber 16556-46-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,6,5,5 and 6 respectively; the second part has 2 digits, 4 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 16556-46:
(7*1)+(6*6)+(5*5)+(4*5)+(3*6)+(2*4)+(1*6)=120
120 % 10 = 0
So 16556-46-0 is a valid CAS Registry Number.

Synthesis of highly substituted cyclohexenes via mixed Lewis acid-catalyzed Diels-Alder reactions of highly substituted dienes and dienophiles

Jung, Michael E.,Ho, David,Chu, Hiufung V.

, p. 1649 - 1651 (2005)

(Chemical Equation Presented) A high-yielding method is described for the rapid synthesis of very hindered cyclohexenes by the Diels-Alder reaction of hindered silyloxy dienes and dienophiles using the mixed Lewis acid catalyst system (AlBr3/AlMe3). Thus, reaction of the hindered diene 4 with various substituted enones gave good yields of the expected cycloadducts even though both partners are quite sterically hindered.
