128935-50-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 128935-50-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,8,9,3 and 5 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 128935-50:
(8*1)+(7*2)+(6*8)+(5*9)+(4*3)+(3*5)+(2*5)+(1*0)=152
152 % 10 = 2
So 128935-50-2 is a valid CAS Registry Number.
