Check Digit Verification of cas no
The CAS Registry Mumber 128350-23-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,8,3,5 and 0 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 128350-23:
(8*1)+(7*2)+(6*8)+(5*3)+(4*5)+(3*0)+(2*2)+(1*3)=112
112 % 10 = 2
So 128350-23-2 is a valid CAS Registry Number.
