Check Digit Verification of cas no
The CAS Registry Mumber 118798-99-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,8,7,9 and 8 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 118798-99:
(8*1)+(7*1)+(6*8)+(5*7)+(4*9)+(3*8)+(2*9)+(1*9)=185
185 % 10 = 5
So 118798-99-5 is a valid CAS Registry Number.

Synthesis of bryophyte components. 3. New syntheses of Perrottetines E, F and G
Eicher,Walter
, p. 469 - 473 (2007/10/02)
Efficient and expeditious syntheses of the Perrottetines E, F and G (4',5-bis(m-hydroxyphenethyl)diphenyl ether derivatives) are developed, which give rise to these biologically active linear bis(bibenzyl) derivatives on a preparative scale.
