Check Digit Verification of cas no

The CAS Registry Mumber 108439-40-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,8,4,3 and 9 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 108439-40:
(8*1)+(7*0)+(6*8)+(5*4)+(4*3)+(3*9)+(2*4)+(1*0)=123
123 % 10 = 3
So 108439-40-3 is a valid CAS Registry Number.

OZONOLYSIS OF ALKENES AND REACTIONS OF POLYFUNCTIONAL COMPOUNDS. XXIX. SYNTHESIS OF ACYCLIC (Z)-1,5-POLYENE ISOPRENOID KETO ACETALS

Odinokov, V. N.,Ignatyuk, V. K.,Krivonogov, V. P.,Tolstikov, G. A.

, p. 848 - 851 (2007/10/02)

A convenient method was developed for the synthesis of acyclic (Z)-1,5-polyene isoprenoid keto acetals on the basis of the partial ozonolysis of regular (Z)-1,4-polyisoprene with subsequent reduction of the peroxides to ω-acetylaldehydes and selective protection of the formyl group.The individual dimethyl acetals of (Z)-1,5-polyene isoprenoid ω-acetylaldehydes with 1-5 (Z)-isoprene units were isolated by vacuum distillation of the mixture of isoprenologs.
