Check Digit Verification of cas no

The CAS Registry Mumber 1310338-91-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,1,0,3,3 and 8 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1310338-91:
(9*1)+(8*3)+(7*1)+(6*0)+(5*3)+(4*3)+(3*8)+(2*9)+(1*1)=110
110 % 10 = 0
So 1310338-91-0 is a valid CAS Registry Number.

Isomerization of diethyl 1-alkynylphosphonates to 1,3-dienylphosphonates followed by diels-alder reaction with dead, maleic anhydride and maleimide

Azab, Abdullatif,Al Aziz Quntar, Abed,Antebi, Tamar,Srebnik, Morris

, p. 417 - 429 (2010)

Isomerization of diethyl 1-alkynylphosphonates, 1, with Pd[(PPh) 3]4 in refluxing 1,4-dioxane provides 1,3- dienylphosphonates, 2, in satisfactory to excellent isolated yield (45-83%). The reaction is tolerant of chlorides and cyclic
