Check Digit Verification of cas no

The CAS Registry Mumber 1296770-69-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,9,6,7,7 and 0 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1296770-69:
(9*1)+(8*2)+(7*9)+(6*6)+(5*7)+(4*7)+(3*0)+(2*6)+(1*9)=208
208 % 10 = 8
So 1296770-69-8 is a valid CAS Registry Number.

RhII2-catalyzed synthesis of α-, β-, or δ-carbolines from aryl azides

Pumphrey, Ashley L.,Dong, Huijun,Driver, Tom G.

, p. 5920 - 5923 (2012/08/07)

Approaching all isomers: A range of α-, β- and δ-carbolinium ions are readily available from ortho-substituted aryl azides using a rhodium(II) carboxylate catalyst (see scheme). The carbolinium ions are readily reduced to afford tryptolines or deprotonated to access pyridoindoles. This [RhII2]-catalyzed C-H bond amination was used in the synthesis of (±)-horsfiline and neocryptolepine. esp=α,α,α',α'- tetramethyl-1,3-benzenedipropionate. Copyright
