Check Digit Verification of cas no

The CAS Registry Mumber 171525-86-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,1,5,2 and 5 respectively; the second part has 2 digits, 8 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 171525-86:
(8*1)+(7*7)+(6*1)+(5*5)+(4*2)+(3*5)+(2*8)+(1*6)=133
133 % 10 = 3
So 171525-86-3 is a valid CAS Registry Number.

Synthesis of C(14',15'), dihydro derivative of the South hexacyclic steroid unit in cephalostatin 1. Part II: Spiroketal synthesis and stereochemical assignment by NMR spectroscopy

Bhandaru,Fuchs

, p. 8351 - 8354 (2007/10/02)

Transformation of aldehyde 3 into 2, a C(14',15'), dihydro analog of the 'South' hexacyclic spiroketal of cephalostatin 1 1 is described. The stereochemistry of 2 was elucidated by NMR spectroscopy.
