Check Digit Verification of cas no
The CAS Registry Mumber 266329-98-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,6,6,3,2 and 9 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 266329-98:
(8*2)+(7*6)+(6*6)+(5*3)+(4*2)+(3*9)+(2*9)+(1*8)=170
170 % 10 = 0
So 266329-98-0 is a valid CAS Registry Number.
