62987-23-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 62987-23-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,2,9,8 and 7 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 62987-23:
(7*6)+(6*2)+(5*9)+(4*8)+(3*7)+(2*2)+(1*3)=159
159 % 10 = 9
So 62987-23-9 is a valid CAS Registry Number.

Enantioselective total synthesis of (-)-decarbamoylsaxitoxin
Hong, Chang Yong,Kishi, Yoshito
, p. 7001 - 7006 (2007/10/02)
An enantioselective total synthesis of (-)-decarbamoylsaxitoxin (2) has been accomplished, using the asymmetric trimolecular cyclization of 6, i.e., 6 + (R)-glyceraldehyde 2,3-acetonide + Si(NCS)4 → α-7, as the key step. The structure of the ma
