Check Digit Verification of cas no
The CAS Registry Mumber 20685-01-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,6,8 and 5 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 20685-01:
(7*2)+(6*0)+(5*6)+(4*8)+(3*5)+(2*0)+(1*1)=92
92 % 10 = 2
So 20685-01-2 is a valid CAS Registry Number.
