21682-90-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 21682-90-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,6,8 and 2 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 21682-90:
(7*2)+(6*1)+(5*6)+(4*8)+(3*2)+(2*9)+(1*0)=106
106 % 10 = 6
So 21682-90-6 is a valid CAS Registry Number.
