142867-83-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 142867-83-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,2,8,6 and 7 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 142867-83:
(8*1)+(7*4)+(6*2)+(5*8)+(4*6)+(3*7)+(2*8)+(1*3)=152
152 % 10 = 2
So 142867-83-2 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
