1009629-25-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1009629-25-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,0,9,6,2 and 9 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1009629-25:
(9*1)+(8*0)+(7*0)+(6*9)+(5*6)+(4*2)+(3*9)+(2*2)+(1*5)=137
137 % 10 = 7
So 1009629-25-7 is a valid CAS Registry Number.

, p. 373 - 376 (2008/09/20)
We report the synthesis and structural characterization of two dispiro compounds. These two positional isomers have been designed and synthesized through an efficient method. Because of the rigidity and orthogonality of the spiro bridge, both molecules ex
