Check Digit Verification of cas no

The CAS Registry Mumber 203259-90-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,3,2,5 and 9 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 203259-90:
(8*2)+(7*0)+(6*3)+(5*2)+(4*5)+(3*9)+(2*9)+(1*0)=109
109 % 10 = 9
So 203259-90-9 is a valid CAS Registry Number.

Engineered P450pyr monooxygenase for asymmetric epoxidation of alkenes with unique and high enantioselectivity

Li, Aitao,Liu, Ji,Pham, Son Q.,Li, Zhi

supporting information, p. 11572 - 11574 (2013/12/04)

A triple mutant of P450pyr monooxygenase (P450pyrTM) catalysed the epoxidation of several para-substituted styrenes as the first enzyme showing high (R)-enantioselectivity and high conversion, demonstrated a broad substrate range, and showed high enantioselectivity for the epoxidation of an unconjugated 1,1-disubstituted alkene, 2-methyl-3-phenyl-1-propene, and a cyclic alkene, N-phenoxycarbonyl-1,2,5,6-tetrahydropyridine, respectively.
