138925-68-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 138925-68-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,8,9,2 and 5 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 138925-68:
(8*1)+(7*3)+(6*8)+(5*9)+(4*2)+(3*5)+(2*6)+(1*8)=165
165 % 10 = 5
So 138925-68-5 is a valid CAS Registry Number.

, p. 941 - 950 (2007/10/02)
The synthesis of the donor-acceptor compounds 2, 7, and 12 where the anthracene donor and the viologen acceptor are linked by a saturated bridge (polymethylene or the bicyclooctanyl moiety) is described.While the preparation of 2a-c is straightforw
