303176-38-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 303176-38-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,0,3,1,7 and 6 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 303176-38:
(8*3)+(7*0)+(6*3)+(5*1)+(4*7)+(3*6)+(2*3)+(1*8)=107
107 % 10 = 7
So 303176-38-7 is a valid CAS Registry Number.
