Check Digit Verification of cas no
The CAS Registry Mumber 421598-88-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,2,1,5,9 and 8 respectively; the second part has 2 digits, 8 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 421598-88:
(8*4)+(7*2)+(6*1)+(5*5)+(4*9)+(3*8)+(2*8)+(1*8)=161
161 % 10 = 1
So 421598-88-1 is a valid CAS Registry Number.

Asymmetric conjugate additions to chiral α,β-unsaturated oxazolines with sulfonyl carbanions
Basil, Laura F,Meyers,Hassner
, p. 207 - 213 (2007/10/03)
Addition of sulfonyl carbanions with or without an electrophilic tether has been shown, under certain conditions, to add to α,β-unsaturated oxazolines in good yields and high de's. When 4-bromobutylsulfonyl carbanions are added to unsaturated oxazolines,
