270918-57-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 270918-57-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,7,0,9,1 and 8 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 270918-57:
(8*2)+(7*7)+(6*0)+(5*9)+(4*1)+(3*8)+(2*5)+(1*7)=155
155 % 10 = 5
So 270918-57-5 is a valid CAS Registry Number.

Synthesis of novel 'push-pull'-enynes
Bacilieri, Christian,Neuenschwander, Markus
, p. 641 - 649 (2007/10/03)
'Push-pull' enynes 14a-d with EtO, PhO, PhS, and MeS groups as π-donors have been synthesized by catalyzed coupling of stannyl ynamines 10 with 3- iodoprop-2-enal (Scheme 4).
