138376-19-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 138376-19-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,8,3,7 and 6 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 138376-19:
(8*1)+(7*3)+(6*8)+(5*3)+(4*7)+(3*6)+(2*1)+(1*9)=149
149 % 10 = 9
So 138376-19-9 is a valid CAS Registry Number.

A Novel Approach to the Synthesis of Enediynes
Magriotis, Plato A.,Scott, Mary E.,Kim, Kee D.
, p. 6085 - 6088 (2007/10/02)
A new method for the synthesis of enediynes is described based on stannylcupration of acetylene and certain activated alkynes, in situ reaction with 1-halo-1-alkynes, iododestannylation, and Pd(0)-catalyzed coupling with terminal alkynes.Key Words: Stanny
