136506-17-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 136506-17-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,6,5,0 and 6 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 136506-17:
(8*1)+(7*3)+(6*6)+(5*5)+(4*0)+(3*6)+(2*1)+(1*7)=117
117 % 10 = 7
So 136506-17-7 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
