640295-19-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 640295-19-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,4,0,2,9 and 5 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 640295-19:
(8*6)+(7*4)+(6*0)+(5*2)+(4*9)+(3*5)+(2*1)+(1*9)=148
148 % 10 = 8
So 640295-19-8 is a valid CAS Registry Number.

Reversible photoswitching of the coordination numbers of silicon in organosilicon compounds bearing a 2-(phenylazo)phenyl group

Kano, Naokazu,Komatsu, Fuminori,Yamamura, Masaki,Kawashima, Takayuki

, p. 7097 - 7109 (2007/10/03)

Several organosilicon compounds bearing a 2-(phenylazo)phenyl group were synthesized from the corresponding chlorosilanes and 2-lithioazobenzene prepared by halogen-lithium transmetalation of 2-iodoazobenzene. Their structures were determined by 1/s
