85669-57-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 85669-57-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,5,6,6 and 9 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 85669-57:
(7*8)+(6*5)+(5*6)+(4*6)+(3*9)+(2*5)+(1*7)=184
184 % 10 = 4
So 85669-57-4 is a valid CAS Registry Number.

PUMMERER REACTION OF BIOTIN SULFOXIDES: AN ACCES TO NEW FUNCTIONALIZED BIOTIN DERIVATIVES.
Lett, Robert,Kuroki, Yoshiaki
, p. 5541 - 5544 (2007/10/02)
Application of the Pummerer reaction to Biotin sulfoxides gives a good acces to the corresponding thiolactol and thiolactone, which are key-compounds for the synthesis of new functionalized Biotin derivatives.
