Check Digit Verification of cas no
The CAS Registry Mumber 130283-83-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,0,2,8 and 3 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 130283-83:
(8*1)+(7*3)+(6*0)+(5*2)+(4*8)+(3*3)+(2*8)+(1*3)=99
99 % 10 = 9
So 130283-83-9 is a valid CAS Registry Number.

Synthesis of N-protected indolaldehydes using modified Hass procedure
Balamurugan, Ramalingam,Mohanakrishnan, Arasambattu K.
, p. 11078 - 11085 (2008/02/12)
A detailed study on oxidation of N-protected bromomethylindoles into the respective aldehydes was carried out. Using a modified Hass procedure, synthesis of aryl-/hetero-aryl aldehydes in particular indolaldehydes is achieved in reasonable yields.
