28124-21-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 28124-21-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,8,1,2 and 4 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 28124-21:
(7*2)+(6*8)+(5*1)+(4*2)+(3*4)+(2*2)+(1*1)=92
92 % 10 = 2
So 28124-21-2 is a valid CAS Registry Number.

, p. 3525 - 3528 (2007/10/03)
Phololysis of 1,2-disila-3,5-cyclohaxadienes 1a-b in the presence of methylene blue as a sensitizer led to efficient formation of the correspondng siloles as ring contraction products. The reaction mechanism is best rationalized by electron-transfer from
