Check Digit Verification of cas no
The CAS Registry Mumber 873653-98-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,7,3,6,5 and 3 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 873653-98:
(8*8)+(7*7)+(6*3)+(5*6)+(4*5)+(3*3)+(2*9)+(1*8)=216
216 % 10 = 6
So 873653-98-6 is a valid CAS Registry Number.
