Check Digit Verification of cas no

The CAS Registry Mumber 137873-04-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,7,8,7 and 3 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 137873-04:
(8*1)+(7*3)+(6*7)+(5*8)+(4*7)+(3*3)+(2*0)+(1*4)=152
152 % 10 = 2
So 137873-04-2 is a valid CAS Registry Number.

Aldolase-catalyzed asymmetric synthesis of novel pyranose synthons as a new entry to heterocycles and epothilones

Liu, Junjie,Wong, Chi-Huey

, p. 1404 - 1407 (2007/10/03)

Enzymatic reactions catalyzed by DERA provide the basis for a new strategy for the synthesis of novel pyranose synthons. The utility of this very convergent and effective method is demonstrated by the concise total synthesis of epothilones (see scheme; DERA = 2-deoxyribose-5-phosphate aldolase).
