Check Digit Verification of cas no

The CAS Registry Mumber 52144-03-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,2,1,4 and 4 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 52144-03:
(7*5)+(6*2)+(5*1)+(4*4)+(3*4)+(2*0)+(1*3)=83
83 % 10 = 3
So 52144-03-3 is a valid CAS Registry Number.

Compounds of the general formula (I): SPC1 in which R1, R2 and R3 may be the same or different and each represents a hdyrogen atom, an alkyl group, a nitro group, a halogen atom or a group of the formula --NR4 R5 or --OR4 ; in which the groups R4 and R5 may be the same or different and each represent a hydrogen atom, or an alkyl, alkenyl or cycloalkyl group (which alkyl group may optionally be substituted by alkoxy, hydroxy, amino, alkylamino, dialkylamino or aryl groups) or R4 and R5 together with the nitrogen atom form a heterocyclic ring which may optionally contain additional hetero atoms, e.g. morpholino or piperazinyl; and R6 represents a hydrogen atom or an alkyl group. These compounds have biological activity, particularly in inhibiting the release of spasmogenic substances arising as a consequence of antigen-antibody reactions.
