257280-74-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 257280-74-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,5,7,2,8 and 0 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 257280-74:
(8*2)+(7*5)+(6*7)+(5*2)+(4*8)+(3*0)+(2*7)+(1*4)=153
153 % 10 = 3
So 257280-74-3 is a valid CAS Registry Number.

Stereoselective syntheses of trans-fused 6,6- and 6,7-membered ether ring systems having an angular methyl group based on SmI2-induced reductive intramolecular cyclization

Matsuo, Goh,Hori, Nobuyuki,Nakata, Tadashi

, p. 8859 - 8862 (2007/10/03)

Highly stereoselective syntheses of trans-fused 6,6- and 6,7-membered ether ring systems having an angular methyl group were achieved based on SmI2-induced reductive intramolecular cyclizations of an aldehyde or a methyl ketone and a β-alkoxy a
