Check Digit Verification of cas no

The CAS Registry Mumber 208448-45-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,8,4,4 and 8 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 208448-45:
(8*2)+(7*0)+(6*8)+(5*4)+(4*4)+(3*8)+(2*4)+(1*5)=137
137 % 10 = 7
So 208448-45-7 is a valid CAS Registry Number.

A chemoselective, acid mediated conversion of amide acetal to oxazole: The key step in the synthesis of cardiovascular drug, ifetroban sodium

Swaminathan, Shankar,Singh, Ambarish K.,Li, Wen-Sen,Venit, John J.,Natalie Jr., Kenneth J.,Simpson, James H.,Weaver, Raymond E.,Silverberg, Lee J.

, p. 4769 - 4772 (1998)

The cyclization of acetal amide was carried out with trimethylsilyl trifluoromethanesulfonate, followed by elimination using sodium methoxide to give 2,5-disubstituted oxazole, thus completing a new route to the cardiovascular drug ifetroban sodium.
