Check Digit Verification of cas no
The CAS Registry Mumber 20826-94-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,8,2 and 6 respectively; the second part has 2 digits, 9 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 20826-94:
(7*2)+(6*0)+(5*8)+(4*2)+(3*6)+(2*9)+(1*4)=102
102 % 10 = 2
So 20826-94-2 is a valid CAS Registry Number.
