Check Digit Verification of cas no
The CAS Registry Mumber 1191419-08-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,9,1,4,1 and 9 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1191419-08:
(9*1)+(8*1)+(7*9)+(6*1)+(5*4)+(4*1)+(3*9)+(2*0)+(1*8)=145
145 % 10 = 5
So 1191419-08-5 is a valid CAS Registry Number.

Page/Page column 15, (2010/08/22)
Cyclic alkynes (e.g., cyclooctynes such as dibenzocyclooctynes) can be photochemically generated from cyclopropenones as disclosed herein. The cyclic alkynes can be reacted (e.g., in situ) with materials having alkyne-reactive groups (e.g., azide groups i
