222026-16-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 222026-16-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,2,0,2 and 6 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 222026-16:
(8*2)+(7*2)+(6*2)+(5*0)+(4*2)+(3*6)+(2*1)+(1*6)=76
76 % 10 = 6
So 222026-16-6 is a valid CAS Registry Number.
