Check Digit Verification of cas no
The CAS Registry Mumber 202921-88-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,2,9,2 and 1 respectively; the second part has 2 digits, 8 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 202921-88:
(8*2)+(7*0)+(6*2)+(5*9)+(4*2)+(3*1)+(2*8)+(1*8)=108
108 % 10 = 8
So 202921-88-8 is a valid CAS Registry Number.
