138622-18-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 138622-18-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,8,6,2 and 2 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 138622-18:
(8*1)+(7*3)+(6*8)+(5*6)+(4*2)+(3*2)+(2*1)+(1*8)=131
131 % 10 = 1
So 138622-18-1 is a valid CAS Registry Number.

Synthesis of 7-Substituted Indoles as Potential Ligand Precursors
Black, David St.C.,Deacon, Glen B.,Edwards, Gavin L.
, p. 1771 - 1781 (2007/10/02)
Some 7-(pyridin-2'-yl)- and 7-(pyrazol-1'-yl)-indole-2-carboxylic esters (14)-(16) and the related acids (17) and (18) have been synthesized through the Fischer indole cyclizations of the ethyl pyruvate hydrazones (9)-(12), which were in turn derived from
