128693-81-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 128693-81-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,8,6,9 and 3 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 128693-81:
(8*1)+(7*2)+(6*8)+(5*6)+(4*9)+(3*3)+(2*8)+(1*1)=162
162 % 10 = 2
So 128693-81-2 is a valid CAS Registry Number.
