Check Digit Verification of cas no

The CAS Registry Mumber 109610-70-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,9,6,1 and 0 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 109610-70:
(8*1)+(7*0)+(6*9)+(5*6)+(4*1)+(3*0)+(2*7)+(1*0)=110
110 % 10 = 0
So 109610-70-0 is a valid CAS Registry Number.

Methyl 4-hydroxy-E-2-alkenoates prepared from aldehydes in one step, undergo the Michael reactions with thiolate anions to give 4-alkanolide derivatives, which are converted into 2-alken-4-olides.Methyl 4-methanesulfonyloxy-E-2-alkenoates undergo the substitution reactions, and subsequent treatments give methyl E,E-2,4-alkadienoates.
