Check Digit Verification of cas no

The CAS Registry Mumber 152212-38-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,2,2,1 and 2 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 152212-38:
(8*1)+(7*5)+(6*2)+(5*2)+(4*1)+(3*2)+(2*3)+(1*8)=89
89 % 10 = 9
So 152212-38-9 is a valid CAS Registry Number.

A series of α-diazo carbonyl compounds tethered to substituted cyclopentanone and cyclohexanone units with different tether lengths have been synthesized using diazomethane solution or methanesulphonyl azide. The above synthesized α-diazo carbonyl compounds with rhodium(II) acetate dimer furnish cyclic five- or six-membered-ring carbonyl ylide dipoles, which undergo facile 1,3-dipolar cycloaddition with p-quinones to furnish various novel oxa-bridged polycyclic systems 10, 13 and 11, 14 as C=C and C=O addition products of p-quinones. Very interesting unusual cyclization product, tri-oxapolycyclic compounds 12 and 15 were also obtained. Single-crystal X-ray analyses of 11a, 12d and 14a are reported to firmly establish the structure and stereochemistry of the oxa-bridged polycyclic systems. The molecules 11a and 14a exhibit novel C-H···O hydrogen bonding motif in the crystal structure. On the other hand, the molecule 12d revealed both O-H···O and C-H···O motifs in the solid-state architecture.
