21663-26-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 21663-26-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,6,6 and 3 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 21663-26:
(7*2)+(6*1)+(5*6)+(4*6)+(3*3)+(2*2)+(1*6)=93
93 % 10 = 3
So 21663-26-3 is a valid CAS Registry Number.
