648418-77-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 648418-77-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,4,8,4,1 and 8 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 648418-77:
(8*6)+(7*4)+(6*8)+(5*4)+(4*1)+(3*8)+(2*7)+(1*7)=193
193 % 10 = 3
So 648418-77-3 is a valid CAS Registry Number.

A Triplet Carbene Surviving a Week in Solution at Room Temperature
Iwamoto, Eri,Hirai, Katsuyuki,Tomioka, Hideo
, p. 14664 - 14665 (2007/10/03)
A stable triplet carbene, having a lifetime at 25 °C of 14.5 days in a dilute benzene solution, was realized by simply changing the substituent at the 10 position of the previously most persistent carbene, di[9-(10-phenyl)anthryl]carbene, from a phenyl to
