Check Digit Verification of cas no
The CAS Registry Mumber 1638-12-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,6,3 and 8 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1638-12:
(6*1)+(5*6)+(4*3)+(3*8)+(2*1)+(1*2)=76
76 % 10 = 6
So 1638-12-6 is a valid CAS Registry Number.

Page/Page column 13, (2011/08/08)
A halogenated non-polymeric phenyl ether is described having the general formula (I): wherein each X is independently Cl or Br, n is an integer of 1 or 2, each m is independently an integer of 1 to 5 and each p is independently an integer of 1 to 4, provided that, when X is Cl, the total amount halogen in the ether is from about 50 to about 65 wt% and when, X is Br, the total amount halogen in the ether is from at least 70 wt % to about 79 wt%.
