Check Digit Verification of cas no

The CAS Registry Mumber 1356557-55-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,5,6,5,5 and 7 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1356557-55:
(9*1)+(8*3)+(7*5)+(6*6)+(5*5)+(4*5)+(3*7)+(2*5)+(1*5)=185
185 % 10 = 5
So 1356557-55-5 is a valid CAS Registry Number.

Orthogonal protecting groups in the synthesis of tryptophanyl- hexahydropyrroloindoles

Ruiz-Sanchis, Pau,Savina, Svetlana A.,Acosta, Gerardo A.,Albericio, Fernando,Alvarez, Mercedes

supporting information; experimental part, p. 67 - 73 (2012/01/15)

The synthesis of various polycyclic systems containing aC 3a-Ni bond between a hexahydropyrrolo[2,3-b]indole and an indole tryptophan is described here. A series of experiments were performed to determine the best combination of five orthogonal protecting groups and the best reaction conditions for formation of said bond, which is a common feature among many recently discovered marine natural products.
