128962-68-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 128962-68-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,8,9,6 and 2 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 128962-68:
(8*1)+(7*2)+(6*8)+(5*9)+(4*6)+(3*2)+(2*6)+(1*8)=165
165 % 10 = 5
So 128962-68-5 is a valid CAS Registry Number.
