Check Digit Verification of cas no

The CAS Registry Mumber 1313899-55-6 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,1,3,8,9 and 9 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1313899-55:
(9*1)+(8*3)+(7*1)+(6*3)+(5*8)+(4*9)+(3*9)+(2*5)+(1*5)=176
176 % 10 = 6
So 1313899-55-6 is a valid CAS Registry Number.

Application of 6,7-indole aryne cycloaddition and Pd(0)-catalyzed Suzuki-Miyaura and Buchwald-Hartwig cross-coupling reactions for the preparation of annulated indole libraries

Thornton, Paul D.,Brown, Neil,Hill, David,Neuenswander, Ben,Lushington, Gerald H.,Santini, Conrad,Buszek, Keith R.

, p. 443 - 448 (2011/11/06)

The construction of an unprecedented class of an indole-based library, namely, a 6,7-annulated-4-substituted 93-member indole library, using a strategic combination of 6,7-indolyne cycloaddition and cross-coupling reactions under both Suzuki-Miyaura and Buchwald-Hartwig conditions is described. This work represents the first example of library development that employs the indole aryne methodology. Annulated indoles, with the exception of only a few biologically active natural products (i.e., the trikentrins, herbindoles, teleocidins, and nodulisporic acids), have no representation in the PubChem or MLSMR databases. These structural entities are therefore predicted to have unique chemical property space characteristics and a high probability of exhibiting interesting biological activity.
