Check Digit Verification of cas no

The CAS Registry Mumber 181271-46-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,1,2,7 and 1 respectively; the second part has 2 digits, 4 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 181271-46:
(8*1)+(7*8)+(6*1)+(5*2)+(4*7)+(3*1)+(2*4)+(1*6)=125
125 % 10 = 5
So 181271-46-5 is a valid CAS Registry Number.

An attempted total synthesis of lysergic acid via an alkene/n-sulfonylimine cyclization

Ralbovsky, Janet L.,Scola, Paul M.,Sugino, Eiichi,Burgos-Garcia, Carolina,Weinreb, Steven M.,Parvez, Masood

, p. 1497 - 1512 (2007/10/03)

Lewis acid-promoted cyclization of the N-tosylimine derived from aldehyde alkene (18) affords an interesting rearranged seven-membered ring tricycle (21) rather than the expected intermediate containing the lysergic acid skeleton.
