Check Digit Verification of cas no

The CAS Registry Mumber 819850-03-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,1,9,8,5 and 0 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 819850-03:
(8*8)+(7*1)+(6*9)+(5*8)+(4*5)+(3*0)+(2*0)+(1*3)=188
188 % 10 = 8
So 819850-03-8 is a valid CAS Registry Number.

Highly enantioselective reaction of α-selenoorganolithium compounds with chiral bis(oxazoline)s and preparation of enantioenriched benzylidencyclohexanes

Nakamura, Shuichi,Aoki, Takayuki,Ogura, Takahiro,Wang, Libo,Toru, Takeshi

, p. 8916 - 8923 (2004)

The enantioselective reaction of α-seleno carbanions derived from bis(phenylseleno)acetal and bis-(2-pyridylseleno)acetal in the presence of bis(oxazoline)s with various electrophiles gave products with high enantioselectivity. The enantioselective reacti
