Check Digit Verification of cas no

The CAS Registry Mumber 821783-01-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,2,1,7,8 and 3 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 821783-01:
(8*8)+(7*2)+(6*1)+(5*7)+(4*8)+(3*3)+(2*0)+(1*1)=161
161 % 10 = 1
So 821783-01-1 is a valid CAS Registry Number.

Novozym 435-catalyzed kinetic resolution of β-allenols. A facile route for the preparation of optically active β-allenols or allenyl acetates

Xu, Daiwang,Lu, Zhan,Li, Zuyi,Ma, Shengming

, p. 11879 - 11887 (2004)

A variety of optically active β-allenols and β-allenyl acetates were synthesized via the Novozym 435-mediated kinetic resolution of racemic β-allenols. A dramatic solvent effect was observed for the stereoselectivity. The scope of the substrates and the e
