Check Digit Verification of cas no
The CAS Registry Mumber 135024-01-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,5,0,2 and 4 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 135024-01:
(8*1)+(7*3)+(6*5)+(5*0)+(4*2)+(3*4)+(2*0)+(1*1)=80
80 % 10 = 0
So 135024-01-0 is a valid CAS Registry Number.

A flexible approach to ecdysteroids, chain elongated at C-26 and C-27, is reported. Key features are the addition of 5-lithio 2,3-dihydrofurans (3) to poststeron (10) and a stereoselective reduction of the 22-∞ group.
