128649-13-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 128649-13-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,8,6,4 and 9 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 128649-13:
(8*1)+(7*2)+(6*8)+(5*6)+(4*4)+(3*9)+(2*1)+(1*3)=148
148 % 10 = 8
So 128649-13-8 is a valid CAS Registry Number.
