Check Digit Verification of cas no

The CAS Registry Mumber 374753-00-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,7,4,7,5 and 3 respectively; the second part has 2 digits, 0 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 374753-00:
(8*3)+(7*7)+(6*4)+(5*7)+(4*5)+(3*3)+(2*0)+(1*0)=161
161 % 10 = 1
So 374753-00-1 is a valid CAS Registry Number.

Stereoselective synthesis of pamamycin-607

Jeong, Eun Jeong,Kang, Eun Joo,Sung, Lee Taek,Hong, Sung Kil,Lee, Eun

, p. 14655 - 14662 (2007/10/03)

A macrodiolide antibiotic pamamycin-607 was synthesized by joining two hydroxy acid components. Three cis-2, 5-disubstituted tetrahydrofuran rings in the molecule were stereoselectively prepared by radical cyclization reactions of β-alkoxyvinyl ketone intermediates and a β-alkoxymethacrylate substrate. The key step of the synthesis is characterized by the predominant threo product formation in the radical cyclization reaction of a β-alkoxymethacrylate intermediate.
