53639-76-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 53639-76-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,3,6,3 and 9 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 53639-76:
(7*5)+(6*3)+(5*6)+(4*3)+(3*9)+(2*7)+(1*6)=142
142 % 10 = 2
So 53639-76-2 is a valid CAS Registry Number.

REGIOCONTROLLED SYNTHESIS OF THE ERGOSTEROL B-ISOMERS
Dolle, Roland E.,Schmidt, Stanley J.,Kruse, Lawrence I.
, p. 1581 - 1582 (2007/10/02)
A novel, regiocontrolled synthesis of the ergosterol B-isomers, (1), (2) and (3) is described, the success of which was realized via the highly regioselective formation of intermediate trienoltriflates, (7), (8) and (9).
