Check Digit Verification of cas no
The CAS Registry Mumber 587854-63-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,8,7,8,5 and 4 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 587854-63:
(8*5)+(7*8)+(6*7)+(5*8)+(4*5)+(3*4)+(2*6)+(1*3)=225
225 % 10 = 5
So 587854-63-5 is a valid CAS Registry Number.
