21658-98-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 21658-98-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,6,5 and 8 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 21658-98:
(7*2)+(6*1)+(5*6)+(4*5)+(3*8)+(2*9)+(1*8)=120
120 % 10 = 0
So 21658-98-0 is a valid CAS Registry Number.
