Check Digit Verification of cas no
The CAS Registry Mumber 203000-48-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,3,0,0 and 0 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 203000-48:
(8*2)+(7*0)+(6*3)+(5*0)+(4*0)+(3*0)+(2*4)+(1*8)=50
50 % 10 = 0
So 203000-48-0 is a valid CAS Registry Number.

(Chemical Equation Presented) trans-1,4-Diphosphacyclohexanes were successfully synthesized by the stereospecific intramolecular coupling reaction of the optically active bisphosphine. This is a new route for the construction of the trans-1,4-diphosphacyclohexane skeleton. A cis isomer was also prepared along with the trans isomer from a mixture of rac- and meso-bisphosphines. The coordinated boranes were easily removed to afford the corresponding 1,4-diphosphacyclohexanes.
