22179-13-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 22179-13-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,2,1,7 and 9 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 22179-13:
(7*2)+(6*2)+(5*1)+(4*7)+(3*9)+(2*1)+(1*3)=91
91 % 10 = 1
So 22179-13-1 is a valid CAS Registry Number.
