49803-30-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 49803-30-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,9,8,0 and 3 respectively; the second part has 2 digits, 3 and 0 respectively.Calculate Digit Verification of CAS Registry Number 49803-30:
(7*4)+(6*9)+(5*8)+(4*0)+(3*3)+(2*3)+(1*0)=137
137 % 10 = 7
So 49803-30-7 is a valid CAS Registry Number.
