Check Digit Verification of cas no
The CAS Registry Mumber 20244-70-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,2,4 and 4 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 20244-70:
(7*2)+(6*0)+(5*2)+(4*4)+(3*4)+(2*7)+(1*0)=66
66 % 10 = 6
So 20244-70-6 is a valid CAS Registry Number.

LASER-STIMULATED CHEMICAL REACTION OF I2 plus C2H2.
Kushawaha
, p. 256 - 258 (1980)
The laser-initiated chemical reaction of I//2 plus C//2H//2 has been studied by exciting the B-X system of the I//2 molecule at 4880, 5145, and 6040 A, using the output from an Ar** plus laser and a CW dye laser pumped by an Ar** plus laser. At 5145 and 4880 A, the reaction products were mostly C//2H//2I//2 and a trace amount of C//2H//2I//4, which was greater at 4880 A than at 5145 A and satisfactorily correlated with the excited iodine atoms produced at these wavelengths; C//2H//2I//2 was the only product at 6040 A. A mechanism for the reaction of the laser-excited I//2 with the C//2H//2 has been proposed and, on the basis of thermal experiments, has been indicated to be nonthermal.
