Check Digit Verification of cas no

The CAS Registry Mumber 1327337-56-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,2,7,3,3 and 7 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1327337-56:
(9*1)+(8*3)+(7*2)+(6*7)+(5*3)+(4*3)+(3*7)+(2*5)+(1*6)=153
153 % 10 = 3
So 1327337-56-3 is a valid CAS Registry Number.

Highly enantioselective hydrogenation of 2-oxo-4-arybutanoic acids to 2-hydroxy-4-arylbutanoic acids

Zhu, Lufeng,Chen, Houhe,Meng, Qinghua,Fan, Weizheng,Xie, Xiaomin,Zhang, Zhaoguo

, p. 6186 - 6190 (2011/09/19)

The Ru-catalyzed asymmetric hydrogenation of 2-oxo-4-arybutanoic acids to afford 2-hydroxy-4-arybutanoic acids was accomplished by employing SunPhos as chiral ligand and 1 M aq HBr as additive. The high enantioselectivities (88.4%-92.6% ee) and efficiency (TON=10,000, TOF=300 h-1) make this method efficient for the synthesis of an important intermediate, (R)-2-hydroxy-4-phenylbutanoic acid, for ACE inhibitors.
