70289-22-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 70289-22-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,0,2,8 and 9 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 70289-22:
(7*7)+(6*0)+(5*2)+(4*8)+(3*9)+(2*2)+(1*2)=124
124 % 10 = 4
So 70289-22-4 is a valid CAS Registry Number.
