Check Digit Verification of cas no

The CAS Registry Mumber 146668-87-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,6,6,6 and 8 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 146668-87:
(8*1)+(7*4)+(6*6)+(5*6)+(4*6)+(3*8)+(2*8)+(1*7)=173
173 % 10 = 3
So 146668-87-3 is a valid CAS Registry Number.

A Practical Synthesis of Perdeuterated Deoxyribose and Deoxyribonucleosides

Goering, Brad K.,Lee, Kwangjin,An, Byungjae,Cha, Jin K.

, p. 1100 - 1103 (2007/10/02)

A stereoselective synthesis of perdeuterated deoxyribofuranoside (1) has been developed starting from known methyl 4-(2'-tetrahydropyranyloxy)-2-butynoate.The synthetic strategy involved the Sharpless asymmetric epoxidation of alcohol 7, followed by a tandem epoxide isomerization and opening with NaCN.The resulting lactone 4b was then reduced via its TBDMS derivative with Dibal-D and subsequently converted to perdeuterated deoxyribofuranoside (1).
