Check Digit Verification of cas no

The CAS Registry Mumber 59284-88-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,9,2,8 and 4 respectively; the second part has 2 digits, 8 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 59284-88:
(7*5)+(6*9)+(5*2)+(4*8)+(3*4)+(2*8)+(1*8)=167
167 % 10 = 7
So 59284-88-7 is a valid CAS Registry Number.

The stereochemistries of the (1S,2E,4S,6E,8S,11E)- and (1S,2E,4R,6E,8S,11E)-2,6,11-cembratriene-4,8-diols (1, 2) have been determined by X-ray analysis.Acid-induced transformations of the 4,8-diols (1, 2) and the (1S,2E,4S,6R,7E,11E)- and (1S,2E,4R,6R,7E,11E)-cembratriene-4,6-diols (3, 4) have been studied.The results show that the 4S,6R- and 4R,6R-diols (3, 4) are interconvertible with the 4S,8S- and 4S,8R-diols (1, 7) and with the 4R,8S-diol (2), respectively.The 4,6-diols (3, 4) also undergo epimerization reactions and a fragmentation reaction yielding a seco-aldehyde (6).
