The CAS Registry Mumber 134249-43-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,4,2,4 and 9 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 134249-43:
(8*1)+(7*3)+(6*4)+(5*2)+(4*4)+(3*9)+(2*4)+(1*3)=117
117 % 10 = 7
So 134249-43-7 is a valid CAS Registry Number.

Asymmetric reductions of (Trifluoroacetyl)biphenyl derivatives with bakers'yeast and with Geotrichum candidum acetone powder

Fujisawa, Tamotsu,Onogawa, Yoshio,Sato, Akira,Mitsuya, Takeshi,Shimizu, Makoto

, p. 4267 - 4276 (1998)

The bakers' yeast reduction of (trifluoroacetyl)biphenyl derivatives produces (R)trifluoromethyl biphenylyl carbinols in high enantioselectivity, whereas the reduction of the same derivatives with Geotrichum candidum acetone powder gives the corresponding (S)-carbinols in excellent yields and enantioselectivity.
