849769-01-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 849769-01-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,4,9,7,6 and 9 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 849769-01:
(8*8)+(7*4)+(6*9)+(5*7)+(4*6)+(3*9)+(2*0)+(1*1)=233
233 % 10 = 3
So 849769-01-3 is a valid CAS Registry Number.

A case of pictet-spengler revisited: Application to the synthesis of dihydroisocoumarins
Choukchou-Braham,Mostefa-Kara,Cheikh,Didi,Villemin
, p. 169 - 178 (2007/10/03)
The reaction of Pictet-Spengler was revisited, and its modified conditions were applied to develop a general methodology toward the synthesis of dihydroisocoumarins containing a no-electron rich aromatic ring.
