308323-83-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 308323-83-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,0,8,3,2 and 3 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 308323-83:
(8*3)+(7*0)+(6*8)+(5*3)+(4*2)+(3*3)+(2*8)+(1*3)=123
123 % 10 = 3
So 308323-83-3 is a valid CAS Registry Number.

Integrated chemical process. Convergent strategy for ortho-phenylene ethynylene skeleton by one-pot double elimination method
Orita,Alonso,Yaruva,Otera
, p. 1333 - 1335 (2007/10/03)
Convergent strategies for ortho-phenylene ethynylene skeletons are realized on the basis of one-pot double elimination method. This protocol overcomes unavoidable difficulties encountered in Sonogashira coupling.
