Check Digit Verification of cas no

The CAS Registry Mumber 210558-22-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,0,5,5 and 8 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 210558-22:
(8*2)+(7*1)+(6*0)+(5*5)+(4*5)+(3*8)+(2*2)+(1*2)=98
98 % 10 = 8
So 210558-22-8 is a valid CAS Registry Number.

Synthesis of some new 3-(chlorophenyl)isocoumarins and their conversion to 3,4-dihydro derivatives

Rama, Nasim H.,Iqbal,Rauf,Rao, Muhammad I.,Zamani,Raza, Abdul R.

, p. 338 - 341 (2007/10/03)

Condensation of homophthalic acid 4 with chlorobenzoyl chlorides 5a-c yields 3-(chlorophenyl)isocoumarins 6a-c which on alkaline hydrolysis give the keto-acids 7a-c. (dl)-3-(Chlorophenyl)-3,4-dihydroisocoumarins 10a-c have been obtained by the reduction of 7a-c to racemic hydroxyacids 9a-c followed by cyclodehydration using acetic anhydride.
