658704-64-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 658704-64-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,5,8,7,0 and 4 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 658704-64:
(8*6)+(7*5)+(6*8)+(5*7)+(4*0)+(3*4)+(2*6)+(1*4)=194
194 % 10 = 4
So 658704-64-4 is a valid CAS Registry Number.
