252033-85-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 252033-85-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,5,2,0,3 and 3 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 252033-85:
(8*2)+(7*5)+(6*2)+(5*0)+(4*3)+(3*3)+(2*8)+(1*5)=105
105 % 10 = 5
So 252033-85-5 is a valid CAS Registry Number.

13-Acetoxy-13-desmethylretinal-14-3H: Synthesis and interaction with bacterioopsin
Seltzer, Stanley
, p. 680 - 685 (2007/10/03)
The title compound (4) was synthesized in three steps from 1,1-dimethoxy-7-methyl-9-(2′,6′,6′-trimethyl-1-cyclohexen-1- yl)-4E,6E,8E-nonatrien-3-one (1). Interaction of 4 with bacterioopsin produced a pigment absorbing at 573 nm, which, on long standing i
