128916-71-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 128916-71-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,8,9,1 and 6 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 128916-71:
(8*1)+(7*2)+(6*8)+(5*9)+(4*1)+(3*6)+(2*7)+(1*1)=152
152 % 10 = 2
So 128916-71-2 is a valid CAS Registry Number.
