Check Digit Verification of cas no

The CAS Registry Mumber 68531-86-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,8,5,3 and 1 respectively; the second part has 2 digits, 8 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 68531-86:
(7*6)+(6*8)+(5*5)+(4*3)+(3*1)+(2*8)+(1*6)=152
152 % 10 = 2
So 68531-86-2 is a valid CAS Registry Number.

SYNTHESIS OF COUMARSABIN AND 4,6,7-TRIMETHOXY-5-METHYL-2H-1-BENZOPYRAN-2-ONE

Venturella, Pietro,Bellino, Aurora,Marino, Maria Luisa

, p. 819 - 822 (2007/10/02)

The condensation of orcinol with methylmalonic acid affords 4,7-dihydroxy-3,5-dimethyl-2H-1-benzopyran-2-one, 4, and 4,5-dihydroxy-3,7-dimethyl-2H-1-benzopyran-2-one, 5.Diazomethane methylation of 4 yields coumarsabin, 1, and 2,7-dimethoxy-3,5-dimethyl-4H-1-benzopyran-4-one, 8.Methylation of 5 gives the coumarin 6 and the chromone 7. 4,6,7-Trimethoxy-5-methyl-2H-1-benzopyran-2-one, 2, a naturally occurring coumarin, has been synthesized from 4,7-dimethoxy-5-methyl-2H-1-benzopyran-2-one (siderin), 3.Alkaline persulphate oxidation of 3 gives 2,5-dihydroxy-4-methoxy-6-methylacetophenone, 9, and 4,6-dihydroxy-5-methyl-7-methoxy-2H-1-benzopyran-2-one, 11, which on methylation with diazomethane gives 2.
