Check Digit Verification of cas no
The CAS Registry Mumber 749153-86-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 7,4,9,1,5 and 3 respectively; the second part has 2 digits, 8 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 749153-86:
(8*7)+(7*4)+(6*9)+(5*1)+(4*5)+(3*3)+(2*8)+(1*6)=194
194 % 10 = 4
So 749153-86-4 is a valid CAS Registry Number.
