Check Digit Verification of cas no

The CAS Registry Mumber 33603-14-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,3,6,0 and 3 respectively; the second part has 2 digits, 1 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 33603-14:
(7*3)+(6*3)+(5*6)+(4*0)+(3*3)+(2*1)+(1*4)=84
84 % 10 = 4
So 33603-14-4 is a valid CAS Registry Number.

1,2-H shift in copper-chlorocarbenoid intermediate during CuCl/bpy-promoted stereoselective dechlorination of 2,2,2-trichloroethyl alkyl ethers to (Z)-1-alkoxy-2-chloroethenes

Ram, Ram N.,Manoj

supporting information; experimental part, p. 2243 - 2246 (2009/05/11)

(Chemical Equation Presented) Reaction of 2,2,2-trichloroethyl alkyl ethers with 2 molar equiv of CuCl/bpy in refluxing DCE yielded (Z)-1-alkoxy-2- chloroethenes stereoselectively as the major product via 1,2-H shift in copper-chlorocarbenoid intermediate. 2,2,2-Trichloroethyl carboxylates undergo a radical 1,2-acyloxy shift under similar conditions.
