Check Digit Verification of cas no

The CAS Registry Mumber 253680-94-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,5,3,6,8 and 0 respectively; the second part has 2 digits, 9 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 253680-94:
(8*2)+(7*5)+(6*3)+(5*6)+(4*8)+(3*0)+(2*9)+(1*4)=153
153 % 10 = 3
So 253680-94-3 is a valid CAS Registry Number.

Enantioselective synthesis of (2S,2'R)-erythro-methylphenidate

Prashad, Mahavir,Liu, Yugang,Kim, Hong-Yong,Repic, Oljan,Blacklock, Thomas J.

, p. 3479 - 3482 (1999)

A new approach towards the enantioselective synthesis of (2S,2'R)- erythro-methylphenidate (1) is described. The key step in the synthesis utilizes Evans' 4-substituted-2-oxazolidinone chiral auxiliary to control the diastereofacial selectivity in the hyd
