76250-84-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 76250-84-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,6,2,5 and 0 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 76250-84:
(7*7)+(6*6)+(5*2)+(4*5)+(3*0)+(2*8)+(1*4)=135
135 % 10 = 5
So 76250-84-5 is a valid CAS Registry Number.

Microbial Stereodifferentiating Reduction of 2,6-Adamantanedione and Hexahydrodibenzoheptalene-5,11-dione, Diketones with Two Homotopic Carbonyl Groups on a C2 Symmetry Axis

Nakazaki, Masao,Chikamatsu, Hiroaki,Nishino, Masayoshi,Murakami, Hiroshi

, p. 1151 - 1156 (1981)

The microbial stereodifferentiating aptitude toward diketones with two homotopic carbonyl groups on a C2 symmetry axis was studied.Incubating of 2,6-adamantanedione (6) with Curvularia lunata yielded, via the ketol 10, (-)-(R)-2,6-adamantanediol (11), and incubation with Rhodotorula rubra converted the (+/-) doubly bridged biphenyl diketone 7 into a mixture of the recovered (+)-(R)-diketone 7, the (+)-(R)-ketol, and the (-)-(S)-cis-diol 19.These stereoselectivities were analyzed to test the proposed "C2-ketone rule".
