21426-37-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 21426-37-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,4,2 and 6 respectively; the second part has 2 digits, 3 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 21426-37:
(7*2)+(6*1)+(5*4)+(4*2)+(3*6)+(2*3)+(1*7)=79
79 % 10 = 9
So 21426-37-9 is a valid CAS Registry Number.
