Check Digit Verification of cas no
The CAS Registry Mumber 889866-98-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,8,9,8,6 and 6 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 889866-98:
(8*8)+(7*8)+(6*9)+(5*8)+(4*6)+(3*6)+(2*9)+(1*8)=282
282 % 10 = 2
So 889866-98-2 is a valid CAS Registry Number.
