128649-26-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 128649-26-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,8,6,4 and 9 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 128649-26:
(8*1)+(7*2)+(6*8)+(5*6)+(4*4)+(3*9)+(2*2)+(1*6)=153
153 % 10 = 3
So 128649-26-3 is a valid CAS Registry Number.
