Check Digit Verification of cas no
The CAS Registry Mumber 889942-73-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,8,9,9,4 and 2 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 889942-73:
(8*8)+(7*8)+(6*9)+(5*9)+(4*4)+(3*2)+(2*7)+(1*3)=258
258 % 10 = 8
So 889942-73-8 is a valid CAS Registry Number.
