Check Digit Verification of cas no

The CAS Registry Mumber 220076-99-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,0,0,7 and 6 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 220076-99:
(8*2)+(7*2)+(6*0)+(5*0)+(4*7)+(3*6)+(2*9)+(1*9)=103
103 % 10 = 3
So 220076-99-3 is a valid CAS Registry Number.

Photo-induced intermolecular radical β-addition to chiral α- (arylsulfinyl) enones

Mase, Nobuyuki

, p. 2957 - 2965 (1998)

The reactions of α-(arylsulfinyl) enones with alkyl radicals having a hydroxy or acetal group were examined under photo-irradiation in the presence of benzophenone. High diastereoselectivity was observed in the photo-induced radical reaction of 2-(arylsulfinyl)-2-cyclopentenones having a bulky aryl group, such as the 2,4,6-triisopropylphenyl or 2,4, 6-trimethylphenyl group. The photo-induced reaction of 3-[(2,4,6-triisopropylphenyl)sulfinyl]-3- pentene-2-one in 1,3-dioxolane also gave a single diastereomer of the 1,3- dioxolan-2-yl adduct.
