Check Digit Verification of cas no
The CAS Registry Mumber 150721-86-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,0,7,2 and 1 respectively; the second part has 2 digits, 8 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 150721-86:
(8*1)+(7*5)+(6*0)+(5*7)+(4*2)+(3*1)+(2*8)+(1*6)=111
111 % 10 = 1
So 150721-86-1 is a valid CAS Registry Number.

Selective magnesiation of chloro-iodopurines: An efficient approach to new purine derivatives
Tobrman, Tomas,Dvorak, Dalimil
, p. 1291 - 1294 (2006)
Both 6-chloro-2-iodo-9-isopropylpurine (1) and 2-chloro-6-iodo-9- benzylpurine (4) undergo a selective I/Mg exchange reaction with iPrMgCl at -80 °C. The reaction course at 0 °C is different. Magnesiation of 1 proceeds with the migration of magnesium to t
