Check Digit Verification of cas no
The CAS Registry Mumber 210095-58-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,0,0,9 and 5 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 210095-58:
(8*2)+(7*1)+(6*0)+(5*0)+(4*9)+(3*5)+(2*5)+(1*8)=92
92 % 10 = 2
So 210095-58-2 is a valid CAS Registry Number.
