128536-67-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 128536-67-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,8,5,3 and 6 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 128536-67:
(8*1)+(7*2)+(6*8)+(5*5)+(4*3)+(3*6)+(2*6)+(1*7)=144
144 % 10 = 4
So 128536-67-4 is a valid CAS Registry Number.
