Check Digit Verification of cas no

The CAS Registry Mumber 173841-92-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,3,8,4 and 1 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 173841-92:
(8*1)+(7*7)+(6*3)+(5*8)+(4*4)+(3*1)+(2*9)+(1*2)=154
154 % 10 = 4
So 173841-92-4 is a valid CAS Registry Number.

Synthesis of Optically Active 2',3'-Dideoxy-3'-oxa-4'-thio-ribonucleoside Analogues by Transposition of a Leaving Group on Chiral Oxathiolanes via a Reductive-oxidative Process

Wang, Wei,Jin, Haolun,Mansour, Tarek S.

, p. 4739 - 4742 (1994)

The synthesis of chiral nucleoside analogues with a unique structural feature is reported.The strategy is based on a reductive-oxidative process to complete the transposition of the leaving group in chiral oxathiolanes with known configuration.
