Check Digit Verification of cas no

The CAS Registry Mumber 618068-05-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,1,8,0,6 and 8 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 618068-05:
(8*6)+(7*1)+(6*8)+(5*0)+(4*6)+(3*8)+(2*0)+(1*5)=156
156 % 10 = 6
So 618068-05-6 is a valid CAS Registry Number.

Total synthesis of seco-lateriflorone

Tisdale, Eric J.,Vong, Binh G.,Li, Hongmei,Kim, Sun Hee,Chowdhury, Chinmay,Theodorakis, Emmanuel A.

, p. 6873 - 6887 (2003)

A convergent strategy toward the synthesis of lateriflorone (5) is described. Our approach is based on biosynthetic considerations and draws on a sequence of prenylation, oxygenation and Claisen reactions for the construction of chromenequinone 6, and a tandem Claisen/Diels-Alder reaction cascade for the synthesis of caged tricycle 7. Union of fragments 6 and 7 led to the synthesis of seco-lateriflorone (49).
