Check Digit Verification of cas no

The CAS Registry Mumber 109107-01-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,9,1,0 and 7 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 109107-01:
(8*1)+(7*0)+(6*9)+(5*1)+(4*0)+(3*7)+(2*0)+(1*1)=89
89 % 10 = 9
So 109107-01-9 is a valid CAS Registry Number.

A number of triazolotriazine derivatives have been prepared. 6-Methyl-3-methylthio-4-triphenylphosphoranylideneamino-5-oxo-4,5-dihydro-1,2,4-triazine (19) reacts with aryl isocyanates to yield the corresponding 1,3-diaryl-2,4-bis-(6-methyl-3-methylthio-5-oxo-4,5-dihydro-1,2,4-triazin-4-ylimino)-1,3-diazetidines (20)-(24); these undergo ring cleavage on treatment with aqueous ethanol to give the 8-aryl-7-arylamino-3-methyltriazolotriazin-4(8H)-ones (8), (12), and (16)-(18).The reaction of the 3-arylmethylenehydrazino-6-methyl-5-oxo-4-triphenylphosphoranylideneamino-4,5-dihydro-1,2,4-triazines (35) and (36), available from the corresponding 4-amino-3-arylmethylenehydrazino-6-methyl-5-oxo-4,5-dihydro-1,2,4-triazine and triphenylphosphine dibromide, with alkyl or aryl isocyanates led directly to 7-arylamino-8-arylmethyleneamino-3-methyltriazolotriazin-4(8H)-ones (37)-(46).Also, iminophosphoranes (5)-(7), (35), and (36) react with acyl chlorides in the presence of triethylamine to give the triazolotriazinones (25)-(31) and (50)-(55) respectively.Structures of compounds (20)-(24) have been established by means of (13)C n.m.r. analysis and X-ray crystallography.
