Check Digit Verification of cas no

The CAS Registry Mumber 202977-10-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,2,9,7 and 7 respectively; the second part has 2 digits, 1 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 202977-10:
(8*2)+(7*0)+(6*2)+(5*9)+(4*7)+(3*7)+(2*1)+(1*0)=124
124 % 10 = 4
So 202977-10-4 is a valid CAS Registry Number.

Cleavage of P=O in the presence of P-N: Aminophosphine oxide reduction with in situ boronation of the PIII product

Kenny, Niall P.,Rajendran, Kamalraj V.,Jennings, Elizabeth V.,Gilheany, Declan G.

supporting information, p. 14210 - 14214 (2013/11/06)

In contrast to tertiary phos-phine oxides, the deoxygenation of aminophosphine oxides is effectively impossible due to the need to break the immensely strong and inert P=O bond in the presence of a relatively weak and more reactive P-N bond. This long-sta
