Check Digit Verification of cas no

The CAS Registry Mumber 156726-71-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,6,7,2 and 6 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 156726-71:
(8*1)+(7*5)+(6*6)+(5*7)+(4*2)+(3*6)+(2*7)+(1*1)=155
155 % 10 = 5
So 156726-71-5 is a valid CAS Registry Number.

Tris(trimethylsilyl)[2H]silane-triethylborane system producing the highly diastereoselective deuteration (> 99:1) of 2'-bromo-2'-deoxy- and 2'-O-phenoxythiocarbonylribonucleosides at 0°C

, p. 7369 - 7372 (2007/10/03)

Reductive protylation and deuteration reactions using (Me3Si)3SiH- and (Me3Si)3Si2H-Et3B systems were investigated in view of the differences in bond energy and bond length between the Si-H of (Me3Si)3SiH and the Sn-H of Bu3SnH. Higher diastereoselectivity was obtained in comparison with the reactions using the Bu3SnH- and Bu3Sn2H-Et3B systems; the (Me3Si)3SiH system gave remarkable diastereoselectivity of 98.7% at 0°C, whereas the other system required temperatures below -70°C.
