Check Digit Verification of cas no

The CAS Registry Mumber 1021499-85-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,2,1,4,9 and 9 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1021499-85:
(9*1)+(8*0)+(7*2)+(6*1)+(5*4)+(4*9)+(3*9)+(2*8)+(1*5)=133
133 % 10 = 3
So 1021499-85-3 is a valid CAS Registry Number.

Tandem annulation strategy for the convergent synthesis of benzonaphthopyranones: total synthesis of chartarin and O-methylhayumicinone

Ray, Sutapa,Patra, Asit,Mal, Dipakranjan

, p. 3253 - 3267 (2008/09/19)

A Hauser-initiated tandem annulation has been developed for the rapid regiospecific synthesis of benzonaphthopyranones via formation of two rings in one-pot operation. This strategy has been generalized with benzonaphthopyranones 26, 29, 32, and 35. It has also been employed in a short synthesis of chartarin (3) and O-methylhayumicinone (67).
