28991-70-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 28991-70-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,8,9,9 and 1 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 28991-70:
(7*2)+(6*8)+(5*9)+(4*9)+(3*1)+(2*7)+(1*0)=160
160 % 10 = 0
So 28991-70-0 is a valid CAS Registry Number.
