Check Digit Verification of cas no
The CAS Registry Mumber 120872-19-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,0,8,7 and 2 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 120872-19:
(8*1)+(7*2)+(6*0)+(5*8)+(4*7)+(3*2)+(2*1)+(1*9)=107
107 % 10 = 7
So 120872-19-7 is a valid CAS Registry Number.

Condensation reaction of 1-oxo-4-chlorocarbonyl-1-phospha-2,6,7-trioxabicyclo[2.2.2]octane with N-t-butyl-N-benzoylhydrazine
Wang, Qingmin,Huang, Runqiu
, p. 173 - 179 (2000)
1-Oxo-4-chlorocarbonyl-l-phospha-2,6,7-trioxabicyclo[2.2.2]octane (5) was obtained from phosphorus oxychloride. Benzyl chloroformate was synthesized by the reaction of benzyl alcohol and triphosgene in good yield for the first time. N-t-Butyl-N-benzoylhydrazine (11) was prepared in a new and convenivent procedure with good yield. The reaction of 5 and 11 proceeded smoothly in the presence of sodium carbonate and afforded the desired compound 13 in good yield, while in the presence of triethylamine, the elimination of butyl was observed and afforded the compound 12.
