Check Digit Verification of cas no

The CAS Registry Mumber 88247-70-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,8,2,4 and 7 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 88247-70:
(7*8)+(6*8)+(5*2)+(4*4)+(3*7)+(2*7)+(1*0)=165
165 % 10 = 5
So 88247-70-5 is a valid CAS Registry Number.

Synthesis of Cholesterol and Derivatives substituted in the Side chain

Kirk, David N.,Varley, Michael J.,Makin, Hugh L.J.,Trafford, David J.H.

, p. 2563 - 2567 (1983)

The carbanion derived from 24-phenylsulphonylchol-5-en-3β-ol 3-tetrahydropyranyl ether (6) reacted with acetone to give the 24-phenylsulphonyl-25-hydroxycholesterol derivative (7a), which was reduced by sodium amalgam to a separable mixture of the labelled 25-hydroxycholesterol and cholest-5,24-dien-3β-ol (desmosterol) derivatives. Cholesterol has been obtained via a selective reduction of the Δ24-unsaturation in desmosteryl benzoate with di-imide, or more efficiently by reducing 25-hydroxycholesteryl 3,25-diacetate w ith litium in ethylamine, without significant loss of label.The labelled 24,25-dihydroxycholesterols were also prepared from desmosteryl benzoate.
