172842-01-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 172842-01-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,2,8,4 and 2 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 172842-01:
(8*1)+(7*7)+(6*2)+(5*8)+(4*4)+(3*2)+(2*0)+(1*1)=132
132 % 10 = 2
So 172842-01-2 is a valid CAS Registry Number.

Enantioselective alkylation of aldehydes catalyzed by new chiral diselenides
Wirth, Thomas
, p. 7849 - 7852 (1995)
New chiral diselenides were synthesized from readily available chiral amines. Their application in the catalytic addition of diethylzinc to aldehydes provided the secondary alcohols in up to 98% ee.
