Check Digit Verification of cas no
The CAS Registry Mumber 7476-99-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,4,7 and 6 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 7476-99:
(6*7)+(5*4)+(4*7)+(3*6)+(2*9)+(1*9)=135
135 % 10 = 5
So 7476-99-5 is a valid CAS Registry Number.

Improved Enantioselectivity of Subtilisin Carlsberg towards Secondary Alcohols by Protein Engineering
Dorau, Robin,G?rbe, Tamás,Svedendahl Humble, Maria
, p. 338 - 346 (2017/12/26)
Generally, the catalytic activity of subtilisin Carlsberg (SC) for transacylation reactions with secondary alcohols in organic solvent is low. Enzyme immobilization and protein engineering was performed to improve the enantioselectivity of SC towards secondary alcohols. Possible amino-acid residues for mutagenesis were found by combining available literature data with molecular modeling. SC variants were created by site-directed mutagenesis and were evaluated for a model transacylation reaction containing 1-phenylethanol in THF. Variants showing high E values (>100) were found. However, the conversions were still low. A second mutation was made, and both the E values and conversions were increased. Relative to that shown by the wild type, the most successful variant, G165L/M221F, showed increased conversion (up to 36 %), enantioselectivity (E values up to 400), substrate scope, and stability in THF.
