Check Digit Verification of cas no
The CAS Registry Mumber 78638-80-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,8,6,3 and 8 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 78638-80:
(7*7)+(6*8)+(5*6)+(4*3)+(3*8)+(2*8)+(1*0)=179
179 % 10 = 9
So 78638-80-9 is a valid CAS Registry Number.

, p. 29 - 40 (2007/10/02)
Substituted methylidenecyclopropanes 12a-d, being easily available from 1,1-dibromo-2-(phenylthio)-cyclopropane (9a), are attractive precursors of triafulvene (2-methylidene-1-cyclopropene; 1).Both the sulfoxide 12b and the sulfone 12c react with an exces
