18734-63-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 18734-63-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,8,7,3 and 4 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 18734-63:
(7*1)+(6*8)+(5*7)+(4*3)+(3*4)+(2*6)+(1*3)=129
129 % 10 = 9
So 18734-63-9 is a valid CAS Registry Number.
