351904-19-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 351904-19-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,5,1,9,0 and 4 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 351904-19:
(8*3)+(7*5)+(6*1)+(5*9)+(4*0)+(3*4)+(2*1)+(1*9)=133
133 % 10 = 3
So 351904-19-3 is a valid CAS Registry Number.

Enantioselective synthesis of bicyclic compounds via catalytic 1,4-addition-ring closing metathesis
Naasz,Arnold,Minnaard,Feringa
, p. 735 - 736 (2001)
A novel three step asymmetric annulation procedure comprises a tandem catalytic enantioselective 1,4-additionallylic substitution, Grignard addition and ring closing metathesis (RCM) sequence to provide [6,6], [7,6], [8,6] and [6,7] bicyclic products with
