128656-76-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 128656-76-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,8,6,5 and 6 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 128656-76:
(8*1)+(7*2)+(6*8)+(5*6)+(4*5)+(3*6)+(2*7)+(1*6)=158
158 % 10 = 8
So 128656-76-8 is a valid CAS Registry Number.
