228104-62-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 228104-62-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,8,1,0 and 4 respectively; the second part has 2 digits, 6 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 228104-62:
(8*2)+(7*2)+(6*8)+(5*1)+(4*0)+(3*4)+(2*6)+(1*2)=109
109 % 10 = 9
So 228104-62-9 is a valid CAS Registry Number.

Synthesis of Functionalised Enamines from α-Thioiminium Salts and Active Methylene Compounds
Singh, Harjit,Batra, M. S.,Singh, Paramjit
, p. 1176 - 1180 (2007/10/02)
Monoprotic and nonprotic α-thioiminium salts react with active methylene compounds under solid liquid phase transfer catalysis (PTC) to give the corresponding enamines in good yields.
