Check Digit Verification of cas no

The CAS Registry Mumber 1609257-77-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,0,9,2,5 and 7 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1609257-77:
(9*1)+(8*6)+(7*0)+(6*9)+(5*2)+(4*5)+(3*7)+(2*7)+(1*7)=183
183 % 10 = 3
So 1609257-77-3 is a valid CAS Registry Number.

Microwave-assisted facile synthesis of [a]-annelated pyrazolopyrroloindoles via intramolecular azomethine imine 1,3-dipolar cycloaddition

Shinde, Anand H.,Vidyacharan, Shinde,Sharada, Duddu S.

, p. 3064 - 3069 (2014/05/20)

The synthesis of [a]-annelated pyrazolopyrroloindoles via intramolecular 1,3-dipolar cycloaddition of in situ generated azomethine imine from N-allylated indole-2-carboxaldehyde, in regio- and stereoselective manner by using microwave irradiation is described. A one-pot strategy for the expedient synthesis of pyrazolopyrroloindoles has been developed.
