222618-88-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 222618-88-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,2,6,1 and 8 respectively; the second part has 2 digits, 8 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 222618-88:
(8*2)+(7*2)+(6*2)+(5*6)+(4*1)+(3*8)+(2*8)+(1*8)=124
124 % 10 = 4
So 222618-88-4 is a valid CAS Registry Number.
