Check Digit Verification of cas no

The CAS Registry Mumber 1395097-35-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,9,5,0,9 and 7 respectively; the second part has 2 digits, 3 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1395097-35:
(9*1)+(8*3)+(7*9)+(6*5)+(5*0)+(4*9)+(3*7)+(2*3)+(1*5)=194
194 % 10 = 4
So 1395097-35-4 is a valid CAS Registry Number.

Total synthesis of (±)-hirsutine: Application of phosphine-catalyzed imine-allene [4 + 2] annulation

Villa, Reymundo A.,Xu, Qihai,Kwon, Ohyun

, p. 4634 - 4637 (2012)

The total synthesis of the indole alkaloid hirsutine has been achieved, with a key step being the application of our phosphine-catalyzed [4 + 2] annulation of an imine with ethyl α-methylallenoate. From commercially available indole-2-carboxaldehyde, the target was synthesized in 14 steps and 6.7% overall yield.
