Check Digit Verification of cas no
The CAS Registry Mumber 4989-27-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,9,8 and 9 respectively; the second part has 2 digits, 2 and 7 respectively.Calculate Digit Verification of CAS Registry Number 4989-27:
(6*4)+(5*9)+(4*8)+(3*9)+(2*2)+(1*7)=139
139 % 10 = 9
So 4989-27-9 is a valid CAS Registry Number.
