Check Digit Verification of cas no

The CAS Registry Mumber 198545-88-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,8,5,4 and 5 respectively; the second part has 2 digits, 8 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 198545-88:
(8*1)+(7*9)+(6*8)+(5*5)+(4*4)+(3*5)+(2*8)+(1*8)=199
199 % 10 = 9
So 198545-88-9 is a valid CAS Registry Number.

Zirconium-catalyzed asymmetric carboalumination of alkenes: ZACA-lipase-catalyzed acetylation synergy

Huang, Zhihong,Tan, Ze,Novak, Tibor,Zhu, Gangguo,Negishi, Ei-Ichi

, p. 539 - 545 (2007)

ZACA-lipase-catalyzed acetylation tandem reactions provide highly efficient and selective routes to either (R)- or (S)-2-methyl-1-alkanols, making, for the first time, the ZACA-based asymmetric synthesis of 2-methyl-1-alkanols widely applicable and satisfactory.
