Check Digit Verification of cas no
The CAS Registry Mumber 641-91-8 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 1 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 641-91:
(5*6)+(4*4)+(3*1)+(2*9)+(1*1)=68
68 % 10 = 8
So 641-91-8 is a valid CAS Registry Number.

1,2,2,5-Tetramethyltetralin and 1,2,2,5,6-pentamethyltetralin have been synthesized and identified as racemates in crude oil and are proposed from dehydrogenation experiments as intermediates in the formation of alkylnaphthalenes in crude oil.
