Check Digit Verification of cas no

The CAS Registry Mumber 137675-64-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,7,6,7 and 5 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 137675-64:
(8*1)+(7*3)+(6*7)+(5*6)+(4*7)+(3*5)+(2*6)+(1*4)=160
160 % 10 = 0
So 137675-64-0 is a valid CAS Registry Number.

Sequential Vinylcyclopropylcarbene and Anionic Oxy-cope Rearrangements: An Expedient Synthesis of Nine-Membered Rings

Herndon, James W.,McMullen, Leonard A.,Daitch, Charles E.

, p. 4547 - 4550 (2007/10/02)

5-Alkenyl-2-methoxy-2-cyclopentenones, readily available from thermolysis of 2-alkenylcyclopropylcarbene-chromium complexes, can be converted to nine-membered rings by treatment with vinylcerium reagents and subsequent anionic oxy-Cope rearrangement.
