138372-05-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 138372-05-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,8,3,7 and 2 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 138372-05:
(8*1)+(7*3)+(6*8)+(5*3)+(4*7)+(3*2)+(2*0)+(1*5)=131
131 % 10 = 1
So 138372-05-1 is a valid CAS Registry Number.

The Second Generation Synthesis of a Tumor Promoter Pendolmycin
Okabe, Kazuaki,Natsume, Mitsutaka
, p. 7615 - 7624 (2007/10/02)
Total synthesis of a tumor promoter pendolmycin (1) was accomplished in the stereospecific manner using a D-serine derivative 7 and an L-valine derivative 16 as chiral sources.Methyl 2-(bromomethyl)benzoate was used for the critical step of the indole cyc
