Check Digit Verification of cas no
The CAS Registry Mumber 126199-80-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,6,1,9 and 9 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 126199-80:
(8*1)+(7*2)+(6*6)+(5*1)+(4*9)+(3*9)+(2*8)+(1*0)=142
142 % 10 = 2
So 126199-80-2 is a valid CAS Registry Number.

REACTIONS OF 2-DIETHYLAMINO-5-METHYL-1,3,2-OXATHIAPHOSPHOLENE WITH PROTON-DONOR REAGENTS AND CHLOROPHOSPHINES
Burilov, A.R.,Nikolaeva, I.L.,Pudovik, M.A.
, p. 685 - 687 (2007/10/02)
The ethanolysis ond phenolysis of 2-diethylamino-5-methyl-1,3,2-oxathiaphospholene were studied.In the first case we observe the initial splitting of the endocyclic P-E bonds, and in the second case the replacement of the dialkylamino group by the phenoxy group, with the cyclic fragment retained.Similarly to the phenolysis, the phospholene reacts with hydrogen chloride and carboxylic acids. 2-Dialkylamino(alkoxy)-1,3,2-oxathiaphospholenes undergo exchange reactions with P(III) chlorides on heating.
