128716-50-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 128716-50-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,8,7,1 and 6 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 128716-50:
(8*1)+(7*2)+(6*8)+(5*7)+(4*1)+(3*6)+(2*5)+(1*0)=137
137 % 10 = 7
So 128716-50-7 is a valid CAS Registry Number.
