Check Digit Verification of cas no
The CAS Registry Mumber 134556-79-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,4,5,5 and 6 respectively; the second part has 2 digits, 7 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 134556-79:
(8*1)+(7*3)+(6*4)+(5*5)+(4*5)+(3*6)+(2*7)+(1*9)=139
139 % 10 = 9
So 134556-79-9 is a valid CAS Registry Number.

Isolation of an isomer of FK-506 from fermentation of Streptomyces tsukubaensis and its chemical synthesis from FK-506
Grassberger, Maximilian A.,Fehr, Theodor,Horvath, Amarylla,Schulz, Gerhard
, p. 413 - 430 (2007/10/02)
From the fermentation broth of Streptomyces tsukubaensis 9993 an isomer 2a of the immunosuppressant FK-506 1a was isolated as a minor metabolite. From NMR- and FAB-MS data follows that in 2a the size of the macrocycle is reduced by two carbon atoms due to
