128694-58-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 128694-58-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,8,6,9 and 4 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 128694-58:
(8*1)+(7*2)+(6*8)+(5*6)+(4*9)+(3*4)+(2*5)+(1*8)=166
166 % 10 = 6
So 128694-58-6 is a valid CAS Registry Number.
