1378374-57-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1378374-57-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,7,8,3,7 and 4 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1378374-57:
(9*1)+(8*3)+(7*7)+(6*8)+(5*3)+(4*7)+(3*4)+(2*5)+(1*7)=202
202 % 10 = 2
So 1378374-57-2 is a valid CAS Registry Number.

, p. 389 - 393 (2012/08/08)
Aspicilin (1), an eighteen membered macrolide with four stereocenters, was synthesized using (3R,4R)- 1,5-hexadiene-3,4-diol and (S)-propylene oxide as the starting materials. Sharpless epoxidation on the protected dienediol generated the required three c
