609820-28-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 609820-28-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,0,9,8,2 and 0 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 609820-28:
(8*6)+(7*0)+(6*9)+(5*8)+(4*2)+(3*0)+(2*2)+(1*8)=162
162 % 10 = 2
So 609820-28-2 is a valid CAS Registry Number.

Multiple functionalization of benzophenones inside polyphenylene dendrimers - Toward entrapped ions and radicals
Bernhardt, Stefan,Baumgarten, Martin,Wagner, Manfred,Muellen, Klaus
, p. 12392 - 12399 (2005)
Polyphenylene dendrimers possessing a defined number of keto groups in the dendritic scaffold have been synthesized by using a benzophenone-functionalized tetraphenylcyclopentadienone branching unit. A postsynthetic functionalization of the polyphenylene
