Check Digit Verification of cas no

The CAS Registry Mumber 135978-98-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,5,9,7 and 8 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 135978-98:
(8*1)+(7*3)+(6*5)+(5*9)+(4*7)+(3*8)+(2*9)+(1*8)=182
182 % 10 = 2
So 135978-98-2 is a valid CAS Registry Number.

REACTIONS WITH 2-METHYL-NAPHTHO-PYRAN-4-ONE AND RELATED SUBSTANCES

Soliman, Ahmed Youssef,Mahmoud, Mahmoud Refai,Bakeer, Hadeer Mohamed

, p. 345 - 354 (2007/10/02)

2-Methyl-naphthopyran-4-one was condensed with various aromatic aldehydes.The 2-styryl derivatives IIa-e allowed to react with maleic anhydride, yielding the tetrahydroxanthone derivatives III.The reactivity of Ia, b and IIIa-d towards hydrazine hydrate, hydrazine derivatives, amines and Grignard reagents was investigated.The IR, and H1 NMR of the products are discussed.
