66348-30-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 66348-30-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,6,3,4 and 8 respectively; the second part has 2 digits, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 66348-30:
(7*6)+(6*6)+(5*3)+(4*4)+(3*8)+(2*3)+(1*0)=139
139 % 10 = 9
So 66348-30-9 is a valid CAS Registry Number.
