Check Digit Verification of cas no

The CAS Registry Mumber 131065-98-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,1,0,6 and 5 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 131065-98:
(8*1)+(7*3)+(6*1)+(5*0)+(4*6)+(3*5)+(2*9)+(1*8)=100
100 % 10 = 0
So 131065-98-0 is a valid CAS Registry Number.

Reaction of Dialkyl Phosphites with α-Enones, II. - 2:1 Adducts from Dimethyl Phosphite and α-Enones: Synthesis of (1-Hydroxy-1,3-alkanediyl)diphosphonates and 5-Dimethoxyphosphoryl-2-methoxy-1,2-oxaphospholane P-Oxides

Oehler, Elisabeth,Zbiral, Erich

, p. 229 - 236 (2007/10/02)

On NaOCH3-catalyzed reaction with two equivalents of dimethyl phosphite (2), various α-enones 1 are transformed into the diphosphonates 5 (e.g. 5a, 5b, 5e, 5f), which, depending on the structure of the enone, can further react with ring closure to give th
