Check Digit Verification of cas no

The CAS Registry Mumber 113334-19-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,3,3,3 and 4 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 113334-19:
(8*1)+(7*1)+(6*3)+(5*3)+(4*3)+(3*4)+(2*1)+(1*9)=83
83 % 10 = 3
So 113334-19-3 is a valid CAS Registry Number.

PREPARATION OF DIHYDROTHIOPYRAN-3-ONES BY ALDOL CONDENSATION OF DIKETO SULFIDES AND ACID-CATALYZED REARRANGEMENT OF KETOL INTERMEDIATES LEADING TO THIOLAN-3-ONE DERIVATIVES

Nakayama, Juzo,Hidaka, Keiko,Hoshino, Masamatsu

, p. 1785 - 1788 (2007/10/02)

Acid-catalyzed intramolecular aldol condensation of diketo sulfides generally affords 2,6-dihydrothiopyran-3-ones and/or their 2,4-dihydro isomers in good yields.The ketol intermediates, in a few cases, undergo sulfur-participated rearrangement to give th
