Check Digit Verification of cas no
The CAS Registry Mumber 70362-47-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,0,3,6 and 2 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 70362-47:
(7*7)+(6*0)+(5*3)+(4*6)+(3*2)+(2*4)+(1*7)=109
109 % 10 = 9
So 70362-47-9 is a valid CAS Registry Number.

, p. 819 - 824 (2007/10/03)
2,2',4,4',5,5'-Hexachlorobiphenyl (HCB) was dechlorinated with potassium-sodium (K-Na) alloy under an inert gas atmosphere. Solvent effect was observed in the reaction. Dechlorination yields in benzene and cyclohexane were 99.9998% and 99.99996%, respecti
