Check Digit Verification of cas no

The CAS Registry Mumber 132639-03-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,2,6,3 and 9 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 132639-03:
(8*1)+(7*3)+(6*2)+(5*6)+(4*3)+(3*9)+(2*0)+(1*3)=113
113 % 10 = 3
So 132639-03-3 is a valid CAS Registry Number.

Formation and Molecular Structure of the 2:1-Adducts of 1-Alkoxy-2-benzopyrylium-4-olates with Carbon Disulfide

Nakano, Hirofumi,Tamura, Hatsue,Ibata, Toshikazu

, p. 771 - 777 (1991)

The Rh2(OAc)4-catalyzed decomposition of alkyl o-(diazoacetyl)benzoates in the presence of carbon disulfide gave two 2:1-adducts of the intermediate 1-alkoxy-2-benzopyrylium-4-olates with carbon disulfide together with a small amount of 5-(o-alkoxycarbony

Formation of 1,3-Oxathiole-2-thione and 1,2,4-Trithiolane Derivatives by the Catalytic Reaction of α-Diazocarbonyl Compounds with Carbon Disulfide

Ibata, Toshikazu,Nakano, Hirofumi

, p. 3096 - 3102 (2007/10/02)

The rhodium(II) acetate-catalyzed decompositin of α-diazocarbonyl compounds such as substituted α-diazoacetophenones, cyclic diazoketones, cyclic diazodiketones, and α-diazo-β-ketoesters in carbon disulfide gave 1,3-dioxathiole-2-thione derivatives in goo
