490026-02-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 490026-02-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,9,0,0,2 and 6 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 490026-02:
(8*4)+(7*9)+(6*0)+(5*0)+(4*2)+(3*6)+(2*0)+(1*2)=123
123 % 10 = 3
So 490026-02-3 is a valid CAS Registry Number.

Kang, Suk-Ku,Ha, Young-Hwan,Yang, Han-Yong
, p. 282 - 283 (2007/10/03)
The palladium(0)-catalysed coupling and cyclisation of allenyl alcohols and allenyl amines with hypervalent iodonium salts afforded cyclised heterocyclic acetals and morpholines under mild conditions.
