Check Digit Verification of cas no

The CAS Registry Mumber 84245-32-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,4,2,4 and 5 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 84245-32:
(7*8)+(6*4)+(5*2)+(4*4)+(3*5)+(2*3)+(1*2)=129
129 % 10 = 9
So 84245-32-9 is a valid CAS Registry Number.

Synthesis of 5,7,11b,12-Tetrahydro-isoindoloisoquinolinium Methiodides and Their Stevens Rearrangement

Ognyanov, Vassil I.,Haimova, Marietta A.,Mollov, Nikola M.

, p. 993 - 998 (2007/10/02)

The title compounds 5 were synthetized in two steps from the corresponding isoindoloisoquinoline-5(7H)-ones 3, obtained in high yields from 3-ethoxy-1H-isoindoles 2 and homophthalic anhydrides 1.The Stevens rearrangement of 5 gave 2-methyl-2,3-dihydro-1H-isoindole-1-spiro-2'-indanes 6. - Keywords: Homophthalic anhydrides; Isoindoloisoquinoline-5(7H)-ones; 2-Methyl-2,3-dihydro-1H-isoindole-1-spiro-2'-indanes; Stevens rearrangement; 5,7,11b,12-Tetrahydro-1H-isoindoloisoquinolines
