Check Digit Verification of cas no

The CAS Registry Mumber 214271-70-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,4,2,7 and 1 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 214271-70:
(8*2)+(7*1)+(6*4)+(5*2)+(4*7)+(3*1)+(2*7)+(1*0)=102
102 % 10 = 2
So 214271-70-2 is a valid CAS Registry Number.

An unprecedented asymmetric Nazarov cyclization for the synthesis of nonracemic indanes as endothelin receptor antagonists

Pridgen, Lendon N.,Huang, Kris,Shilcrat, Susan,Tickner-Eldridge, Ann,DeBrosse, Charles,Haltiwanger, R. Curtis

, p. 1612 - 1614 (1999)

An asymmetric synthesis of the novel nonracemic endothelin receptor antagonists, SB 209670 (1a) and SB 217242 (1b) is described which utilizes an unprecedented asymmetric Nazarovtype ring closure of the alkylidene-1,3- carbonyl compounds. Excellent 1,5-induction is observed which establishes the required S configuration at the C-3 carbon of an indane skeleton.
