Check Digit Verification of cas no

The CAS Registry Mumber 110789-58-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,0,7,8 and 9 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 110789-58:
(8*1)+(7*1)+(6*0)+(5*7)+(4*8)+(3*9)+(2*5)+(1*8)=127
127 % 10 = 7
So 110789-58-7 is a valid CAS Registry Number.

SYNTHESIS OF 1-SUBSTITUTED 1,2,3,9a-TETRAHYDRO-9H-IMIDAZOINDOL-2-ONES

Shachkus, A. A.,Degutis, Yu. A.

, p. 1198 - 1202 (2007/10/02)

1-R-9,9,9a-Trimethyl-1,2,3,9a-tetrahydro-9H-imidazoindol-2-ones and the corresponding 2-methylene-2,3-dihydroindoles were obtained by the reaction of 2,3,3-trimethyl-3H-indole with a number of N-substituted chloroacetic acid amides and subsequent reaction of the resulting quartenary salts with bases.The kinetics of intramolecular cyclization of 1-(N-alkylcarbamoylethyl)-2-methylene-2,3-dihydroindoles under the influence of acetic acid were studied.Under the influence of strong protic acids 1-R-imidazoindol-2-ones undergo decyclization and are converted to 3H-indolium salts.
