Check Digit Verification of cas no
The CAS Registry Mumber 1353745-28-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,5,3,7,4 and 5 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1353745-28:
(9*1)+(8*3)+(7*5)+(6*3)+(5*7)+(4*4)+(3*5)+(2*2)+(1*8)=164
164 % 10 = 4
So 1353745-28-4 is a valid CAS Registry Number.

Terminal alkyne addition to diazodicarboxylates: Synthesis of hydrazide linked alkynes (ynehydrazides)
Beveridge, Ramsay E.,Batey, Robert A.
, p. 540 - 543 (2012/03/26)
A new route to form Csp-N bonds has been developed via addition of in situ generated lithium acetylides to sterically hindered diazodicarboxylates. The reaction provides straightforward access to a previously unexplored ynehydrazide class of st
