Check Digit Verification of cas no

The CAS Registry Mumber 138145-91-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,8,1,4 and 5 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 138145-91:
(8*1)+(7*3)+(6*8)+(5*1)+(4*4)+(3*5)+(2*9)+(1*1)=132
132 % 10 = 2
So 138145-91-2 is a valid CAS Registry Number.

A NEW ROUTE TO γ-SUBSTITUTED γ-LACTONES AND δ-SUBSTITUTED δ-LACTONES BASED ON THE REGIOSELECTIVE β-SCISSION OF ALKOXY RADICALS GENERATED FROM TRANSANNULAR HEMIACETALS

Kobayashi, Kazuhiro,Sasaki, Akiyoshi,Kanno, Yoshikazu,Suginome, Hiroshi

, p. 7245 - 7258 (1991)

A new general synthesis of γ-substituted γ-lactones and δ-substituted δ-lactones including dihydro-5-octyl-2(3H)-furanone, a natural pheromone, is described.The synthesis involves the regioselective β-scission of alkoxy radicals generated from transannular hemiacetals as the key step. Key Words: γ-Lactones; δ-Lactones; Mercury(II) Oxide-Iodine Reagent; Photolysis; β-Scission of Alkoxyl Radicals
