78536-37-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 78536-37-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,8,5,3 and 6 respectively; the second part has 2 digits, 3 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 78536-37:
(7*7)+(6*8)+(5*5)+(4*3)+(3*6)+(2*3)+(1*7)=165
165 % 10 = 5
So 78536-37-5 is a valid CAS Registry Number.

Sun, Han-dong,Sun, Xi-chang,Lin, Zhon-wen,Xu, Yan-long,Minami, Yoshinori,et al.
, p. 753 - 756 (2007/10/02)
Chemical investigation of the bitter principles from Rabdosia Excisa has led to the isolation and characterization of two new diterpenoids having an ent-kaurene skeleton, excisanin A and B, and their structures were established by spectroscopic and chemical data.
