406226-17-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 406226-17-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,0,6,2,2 and 6 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 406226-17:
(8*4)+(7*0)+(6*6)+(5*2)+(4*2)+(3*6)+(2*1)+(1*7)=113
113 % 10 = 3
So 406226-17-3 is a valid CAS Registry Number.

Asymmetric synthesis of cis-aminochromanol
Hansen, Karl B.,Rabbat, Philippe,Springfield, Shawn A.,Devine, Paul N.,Grabowski, Edward J.J.,Reider, Paul J.
, p. 8743 - 8745 (2001)
An efficient asymmetric synthesis of cis-aminochromanol was achieved in seven steps. The absolute stereochemistry of cis-aminochromanol was derived from (salen)Co(III)-catalyzed phenol opening of methyl glycidate.
