Check Digit Verification of cas no

The CAS Registry Mumber 274250-87-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,7,4,2,5 and 0 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 274250-87:
(8*2)+(7*7)+(6*4)+(5*2)+(4*5)+(3*0)+(2*8)+(1*7)=142
142 % 10 = 2
So 274250-87-2 is a valid CAS Registry Number.

Total synthesis of optically active m-phenylene PGl2 derivative: Beraprost

Wakita, Hisanori,Yoshiwara, Hideo,Nishiyama, Hisao,Nagase, Hiroshi

, p. 1085 - 1110 (2007/10/03)

The optical isomers of m-phenylene PGl2 derivative, Beraprost, were synthesized in practical scales from optically active carboxy- cyclopenta[b]benzofurans (12 and 13) by Wittig and Wadsworth reactions as key reactions via the intermediate diols (16a and 16b).
