Check Digit Verification of cas no

The CAS Registry Mumber 127899-29-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,7,8,9 and 9 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 127899-29:
(8*1)+(7*2)+(6*7)+(5*8)+(4*9)+(3*9)+(2*2)+(1*9)=180
180 % 10 = 0
So 127899-29-0 is a valid CAS Registry Number.

Cycloadditions between Electron-poor Phospha-alkene Complexes and Electron-rich Alkenes or Alkynes: A New Route to Phosphetane and 1,2-Dihydrophosphete Rings

Marinetti, Angela,Mathey, Francois

, p. 153 - 154 (2007/10/02)

Ethoxycarbonyl-C-substituted phospha-alkene P-W(CO)5 complexes instantly react at low temperature with enamines, enol ethers, ynamines, and ethoxyacetylene to yield the corresponding phosphetane and 1,2-dihydrophosphete cycloadducts.
