Check Digit Verification of cas no
The CAS Registry Mumber 38770-37-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,8,7,7 and 0 respectively; the second part has 2 digits, 3 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 38770-37:
(7*3)+(6*8)+(5*7)+(4*7)+(3*0)+(2*3)+(1*7)=145
145 % 10 = 5
So 38770-37-5 is a valid CAS Registry Number.

Double (internal/external) alkyne insertion reactions of α-diazoketones
Hoye,Dinsmore
, p. 3755 - 3758 (2007/10/02)
Acetylenic α-diazoketone 5, when treated with Rh2(OAc)4 and several different alkynes, gives alkyne insertion/cyclopropenation products. Subsequent catalytic ring opening reactions demonstrate a highly regioselective net double alkyn
