Check Digit Verification of cas no

The CAS Registry Mumber 873656-95-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,7,3,6,5 and 6 respectively; the second part has 2 digits, 9 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 873656-95:
(8*8)+(7*7)+(6*3)+(5*6)+(4*5)+(3*6)+(2*9)+(1*5)=222
222 % 10 = 2
So 873656-95-2 is a valid CAS Registry Number.

A new entry to the synthesis of 2,3-disubstituted indoles

Mukai, Chisato,Takahashi, Yukie

, p. 5793 - 5796 (2007/10/03)

(Chemical Equation Presented) The Stille coupling of N-acyl-2-iodoanilines with the 1-(tributylstannyl)-1-substituted allenes affected the successive one-step formation of the 2-methyl-3-substituted indoles. Alternatively, the other type of 2-alkyl-3-substituted indoles could be synthesized in a one-pot operation, which consists of the Stille coupling reaction with the 1-(tributylstannyl)-1,3-disubstituted allenes, followed by TBAF treatment. This procedure could be applied to the synthesis of indomethacin.
