Check Digit Verification of cas no
The CAS Registry Mumber 78303-29-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,8,3,0 and 3 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 78303-29:
(7*7)+(6*8)+(5*3)+(4*0)+(3*3)+(2*2)+(1*9)=134
134 % 10 = 4
So 78303-29-4 is a valid CAS Registry Number.

NOUVELLE ORIENTATION DE LA REACTION DES YLURES DU PHOSPHORE AVEC LES ALDEHYDES
Kolodiazhnyi, Oleg I.
, p. 1231 - 1234 (2007/10/02)
A new reaction of ylids 1 with aldehydes is described.C-monosubstituted ylids t-Bu2P(Cl)=CH-R' give with aldehydes R''CH=O the phosphine oxydes t-Bu2P(O)-CH(Cl)R''stereoselectively ; the assymetric ylids t-Bu(R2N)P(Cl)=CH2 give a mixture of diastereoisomers.
