Check Digit Verification of cas no

The CAS Registry Mumber 452068-49-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,5,2,0,6 and 8 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 452068-49:
(8*4)+(7*5)+(6*2)+(5*0)+(4*6)+(3*8)+(2*4)+(1*9)=144
144 % 10 = 4
So 452068-49-4 is a valid CAS Registry Number.

The compounds have the following general formula (I): [wherein: A1, A3 and A4 are hydrogen atom, halogen atom, alkyl group having one to five carbon atoms, alkoxy group having one to five carbon atoms, -COOR1, a following formula (wherein: R1 is hydrogen atom or alkyl group having one to five carbon atoms) or a following formula [wherein: R2 is -CH2OH group, -CH2OC(O)-R1 group or -CO2-R1 group; R3 is -OH group or-OC(O)-R1 group; R4 is -(CH2)kR5(CH2)1- (k and 1 are 0 or 1 more integer; k+1 is 10 or fewer integer); R5 means bond (single bond (-), -CH=CH-, -OCH2-, carbonyl group or -CH(OH)-.]. One of A1, A3 and A4 in formula (I) is must be the group in above mentioned formula (a). A2 is alkyl chain having one to five carbon atoms, alkoxy chain having one to five carbon atoms, alkenyl chain having one to five carbon atoms, hydroxyalkyl chain having one to five carbon atoms or carbonylalkyl chain having one to five carbon atoms. n, p, q or r are 0, 1 or 2.] or their pharmaceutical acceptable salts.
