Check Digit Verification of cas no

The CAS Registry Mumber 1620151-46-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,2,0,1,5 and 1 respectively; the second part has 2 digits, 4 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1620151-46:
(9*1)+(8*6)+(7*2)+(6*0)+(5*1)+(4*5)+(3*1)+(2*4)+(1*6)=113
113 % 10 = 3
So 1620151-46-3 is a valid CAS Registry Number.

Lewis Acid Catalyzed Tandem Polycyclization of Internal Alkynols and Vinyl Azides

Siyang, Hai Xiao,Ji, Xiao Yue,Wu, Xu Rui,Wu, Xin Yan,Liu, Pei Nian

, p. 5220 - 5223 (2015)

A novel Lewis acid catalyzed tandem cyclization reaction of internal alkynols and vinyl azides has been achieved to afford a series of products containing a pyran-based indeno[1,2-c]isochromene scaffold in moderate to high yields. This tandem polycyclization protocol provides a straightforward entry to construct the complex polycyclic skeleton through cycloisomerization, formal [4 + 2] cycloaddition, and an elimination process.
