Check Digit Verification of cas no
The CAS Registry Mumber 642-96-6 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 6,4 and 2 respectively; the second part has 2 digits, 9 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 642-96:
(5*6)+(4*4)+(3*2)+(2*9)+(1*6)=76
76 % 10 = 6
So 642-96-6 is a valid CAS Registry Number.

-
, (2008/06/13)
A bioengineered synthesis scheme for the production of 1,2,3,4-tetrahydroxybenzene from a carbon source is provided. Methods of producing 1,2,3,4-tetrahydroxybenzene acid from a carbon source based on the synthesis scheme are also provided. Methods are also provided for converting 1,2,3,4-tetrahydroxybenzene to 1,2,3-trihydroxybenzene by catalytic hydrogenation.
