21170-94-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 21170-94-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,1,7 and 0 respectively; the second part has 2 digits, 9 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 21170-94:
(7*2)+(6*1)+(5*1)+(4*7)+(3*0)+(2*9)+(1*4)=75
75 % 10 = 5
So 21170-94-5 is a valid CAS Registry Number.
