Check Digit Verification of cas no

The CAS Registry Mumber 131742-09-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,1,7,4 and 2 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 131742-09:
(8*1)+(7*3)+(6*1)+(5*7)+(4*4)+(3*2)+(2*0)+(1*9)=101
101 % 10 = 1
So 131742-09-1 is a valid CAS Registry Number.

The invention relates to compounds of formula I: STR1 in which m=2-4, n and p, which may be identical or different, are an integer equal to 1, 2 or 3, with the proviso that the sum of n and p is not less than 3 and not more than 5, q=0 or 1, R is a 1,2,3,4-tetrahydro-3-quinazolinyl radical, optionally substituted, a 1,3,4,6,11,11a-hexahydro-1,3-dioxo-2H-pyrazino[1,2,-b]isoquinol-2-yl radical, a 1,2-dihydro-1-oxo-2-phthalazinyl radical, optionally substituted, a 2,6-dioxo-1-piperazinyl radical of formula W: STR2 (R3 is a 2-pyridyl radical or an optionally substituted phenyl radical), a radical of formula Z: STR3 (R4 is a carbamoyl radical, a cyano radical, a hydroxycarbonyl radical or an alkoxycarbonyl radical having 1 to 6 carbon atms), or a radical of formula Y: STR4 (R5 is a 2-pyrimidinyl radical, a 1-isoquinolyl radical, a 2-quinolyl radical, a 2-pyridyl radical, a benzyl radical, optionally substituted, a 2-thiazolyl radical, optionally substituted, or a 2-benzothiazolyl radical) and either R1 and R2, identical or different, each are a substituted phenyl radical, or R1 is a phenyl radical and R2 a 2-pyridyl radical (it being possible for each of these two radicals to be substituted), or R1 and R2, together with the carbon atom to which they are attached, form a fluorene radical.
