181940-93-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 181940-93-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,1,9,4 and 0 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 181940-93:
(8*1)+(7*8)+(6*1)+(5*9)+(4*4)+(3*0)+(2*9)+(1*3)=152
152 % 10 = 2
So 181940-93-2 is a valid CAS Registry Number.

Preparation of specifically deuterated RNA for NMR studies using a combination of chemical and enzymatic synthesis
Tolbert, Thomas J.,Williamson, James R.
, p. 7929 - 7940 (1996)
The syntheses of ATP, GTP, UTP, and CTP with deuterium labels on the 3', 4', and 5' carbons (2-5) is described. A combination of chemical and enzymatic synthesis is used where D,L-ribose-3,4,5,5'-d4 (±1) is first produced from glycerol-d8
