Check Digit Verification of cas no

The CAS Registry Mumber 139726-18-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,9,7,2 and 6 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 139726-18:
(8*1)+(7*3)+(6*9)+(5*7)+(4*2)+(3*6)+(2*1)+(1*8)=154
154 % 10 = 4
So 139726-18-4 is a valid CAS Registry Number.

PHOSPHORYLATION OF 1-MORPHOLINOCYCLOHEXENE AND CYCLOPENTENE. CONVENIENT METHOD OF SYNTHESIS OF α-PHOSPHORYLATED DERIVATIVES OF CYCLOHEXANONE AND CYCLOPENTANONE

Tolmachev, A. A.,Kostyuk, A. N.,Morozova, L. N.,Lampeka, R. D.,Kozlov, E. S.,Pinchuk, A. M.

, p. 1475 - 1484 (2007/10/02)

It was shown that 1-morpholinocyclopentene and 1-morpholinocyclohexene are readily phosphorylated by phosphorus(III) halides in the presence of triethylamine.From the compounds obtained, α-phosphorylated cyclopentanones and cyclohexanones were synthesized
