Check Digit Verification of cas no
The CAS Registry Mumber 21905-86-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,9,0 and 5 respectively; the second part has 2 digits, 8 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 21905-86:
(7*2)+(6*1)+(5*9)+(4*0)+(3*5)+(2*8)+(1*6)=102
102 % 10 = 2
So 21905-86-2 is a valid CAS Registry Number.
