21932-59-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 21932-59-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,9,3 and 2 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 21932-59:
(7*2)+(6*1)+(5*9)+(4*3)+(3*2)+(2*5)+(1*9)=102
102 % 10 = 2
So 21932-59-2 is a valid CAS Registry Number.

The Methylene Blue-Sensitized Photooxidation of Quadricyclane, Reinvestigated
Hatsui, Toshihide,Takeshita, Hitoshi
, p. 1253 - 1254 (2007/10/02)
Photooxygenation of quadricyclane (1) was shown to proceed via the electron transfer mechanism on the basis of the structure revision of a methoxy alcohol.Photoisomerization of 1 to norbornadiene occurred during the irradiation.
