73684-08-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 73684-08-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,3,6,8 and 4 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 73684-08:
(7*7)+(6*3)+(5*6)+(4*8)+(3*4)+(2*0)+(1*8)=149
149 % 10 = 9
So 73684-08-9 is a valid CAS Registry Number.
