270923-44-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 270923-44-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,7,0,9,2 and 3 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 270923-44:
(8*2)+(7*7)+(6*0)+(5*9)+(4*2)+(3*3)+(2*4)+(1*4)=139
139 % 10 = 9
So 270923-44-9 is a valid CAS Registry Number.
