Check Digit Verification of cas no

The CAS Registry Mumber 122941-10-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,2,9,4 and 1 respectively; the second part has 2 digits, 1 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 122941-10:
(8*1)+(7*2)+(6*2)+(5*9)+(4*4)+(3*1)+(2*1)+(1*0)=100
100 % 10 = 0
So 122941-10-0 is a valid CAS Registry Number.

METHOD FOR PRODUCING POLYHYDRIC PHENOL

-

Page/Page column 15, (2012/03/10)

The present invention is a method for producing a polyhydric phenol, including the following steps (a) to (d): (a) a first step of producing (4S,5R,6S)-4,5,6-trihydroxy-2-cyclohexcene-1-one from 2-deoxy-scyllo-inosose by a dehydration reaction; (b) a second step of producing 1,2,4-trihydroxybenzene from the (4S,5R,6S)-4,5,6-trihydroxy-2-cyclohexene-1-one obtained in the first step by a dehydration reaction; (c) a third step of producing 4-hydroxycyclohexane-1,3-dione from the 1,2,4-trihydroxybenzene by a catalytic hydrogenation reaction with the use of a metal catalyst; and (d) a fourth step of producing hydroquinone by heating the 4-hydroxycyclohexane-1,3-dione.
