Check Digit Verification of cas no
The CAS Registry Mumber 869563-54-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,6,9,5,6 and 3 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 869563-54:
(8*8)+(7*6)+(6*9)+(5*5)+(4*6)+(3*3)+(2*5)+(1*4)=232
232 % 10 = 2
So 869563-54-2 is a valid CAS Registry Number.
