309730-54-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 309730-54-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,0,9,7,3 and 0 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 309730-54:
(8*3)+(7*0)+(6*9)+(5*7)+(4*3)+(3*0)+(2*5)+(1*4)=139
139 % 10 = 9
So 309730-54-9 is a valid CAS Registry Number.
