Check Digit Verification of cas no

The CAS Registry Mumber 107920-30-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,7,9,2 and 0 respectively; the second part has 2 digits, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 107920-30:
(8*1)+(7*0)+(6*7)+(5*9)+(4*2)+(3*0)+(2*3)+(1*0)=109
109 % 10 = 9
So 107920-30-9 is a valid CAS Registry Number.

OXIME ESTERS AND PHOTOPOLYMERIZATION INITIATORS CONTAINING THE SAME

-

Page/Page column 19; 20, (2010/09/17)

An oxime ester compound of formula (I) useful as a photopolymerization initiator. A photopolymerization initiator having the oxime ester compound as an active ingredient is activated through efficient absorption of light of long wavelength, e.g., 405 nm or 365 nm, to exhibit high sensitivity. In formula (I), R1 and R2 are each R11, OR11, COR11, SR11, CONR12R13, or CN; R11, R12, and R13 are each hydrogen, a C1-C20 alkyl group, C6-C30 aryl group, a C7-C30 arylalkyl group, or a C2-C20 heterocyclic group; R3 and R4 are each R11, OR11, SR11, COR11, CONR12R13, NR12COR11, OCOR11, COOR11, SCOR11, OCSR11, COSR11, CSOR11, CN, halogen, or a hydroxyl group; a and b is each 0 to 4; X is oxygen, sulfur, selenium, CR31R32, CO, NR33, or PR34; and R31, R32, R33, and R34 each have the same meaning as R1.
