Check Digit Verification of cas no
The CAS Registry Mumber 24720-64-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,4,7,2 and 0 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 24720-64:
(7*2)+(6*4)+(5*7)+(4*2)+(3*0)+(2*6)+(1*4)=97
97 % 10 = 7
So 24720-64-7 is a valid CAS Registry Number.

Phosphonium ylides 1 react with tetramethylformamidinium chloride (2) to form enamine phosphonium chlorides 8 and the formic orthoamide 7.The salts 8 show temperature depending 1H NMR spectra with respect to the protons of the dimethylamino group (hindered rotation around the C - N(CH3)2 bond).Treatment of 8 with acids and subsequently with bases gives rise to the formation of the formyl ylides 19. 8a is deprotonated with sodium amide to give the phosphaallene ylide 20, which reacts with water to yield the phosphane oxide 21, and with methyl iodide stereospecifically to form 8b.
