128478-22-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 128478-22-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,8,4,7 and 8 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 128478-22:
(8*1)+(7*2)+(6*8)+(5*4)+(4*7)+(3*8)+(2*2)+(1*2)=148
148 % 10 = 8
So 128478-22-8 is a valid CAS Registry Number.
