Check Digit Verification of cas no
The CAS Registry Mumber 135339-04-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,5,3,3 and 9 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 135339-04:
(8*1)+(7*3)+(6*5)+(5*3)+(4*3)+(3*9)+(2*0)+(1*4)=117
117 % 10 = 7
So 135339-04-7 is a valid CAS Registry Number.

A one-step approach to 1-(fluoroalkyl)indolizine derivatives
Zhang, Xue-Chun,Huang, Wei-Yuan
, p. 51 - 54 (1999)
A facile one-step method is presented for the synthesis of 1- (fluoroalkyl)-substituted indolizine derivatives in moderate to good yields by reactions of pyridinium, 4-methylpyridinium, isoquinolinium, and pyridazinium ylides with 2-bromo-3,3,3-trifluorop
