Check Digit Verification of cas no

The CAS Registry Mumber 258846-76-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,5,8,8,4 and 6 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 258846-76:
(8*2)+(7*5)+(6*8)+(5*8)+(4*4)+(3*6)+(2*7)+(1*6)=193
193 % 10 = 3
So 258846-76-3 is a valid CAS Registry Number.

A new diastereoselective synthesis of a 1β-methylcarbapenem intermediate

Oh, Chang-Young,Ham, Won-Hun

, p. 2365 - 2366 (2007/10/03)

A 1β-methylcarbapenem key intermediate is synthesized from methyl (R)- 3-hydroxybutyrate via the diastereoselective alkylation and regioselective cuprate ring opening of a chiral epoxide which is readily prepared from Sharpless asymmetric epoxidation of the corresponding allylic alcohol.
