40317-65-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 40317-65-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,0,3,1 and 7 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 40317-65:
(7*4)+(6*0)+(5*3)+(4*1)+(3*7)+(2*6)+(1*5)=85
85 % 10 = 5
So 40317-65-5 is a valid CAS Registry Number.

Excited-state proton transfer and excited-state de-hydrogen bonding of the push-pull styryl system
Wang, Shun-Li,Gao, Guo-Yi,Ho, Tong-Ing,Yang, Li-Yu
, p. 217 - 222 (2005)
The excited-state reaction of push-pull styryl system was studied in this work. In the excited state, compounds of 2-StP-NMe2, 2-StQ-NMe 2, 4-StQ-NMe2 and 4-StP-NMe2 possess a sufficiently large acidity change f
