Check Digit Verification of cas no
The CAS Registry Mumber 190438-03-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,0,4,3 and 8 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 190438-03:
(8*1)+(7*9)+(6*0)+(5*4)+(4*3)+(3*8)+(2*0)+(1*3)=130
130 % 10 = 0
So 190438-03-0 is a valid CAS Registry Number.

, p. 5095 - 5099 (2007/10/03)
Single-crystal X-ray analysis of 1-(2,4,6-tri-tert-butylphenyl)-3- methylphosphole, synthesized to test the effect of the strongly sterically demanding P-substituent on the geometry of the molecule, revealed that the phosphorus pyramid was drastically fla
