Check Digit Verification of cas no
The CAS Registry Mumber 118644-90-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,8,6,4 and 4 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 118644-90:
(8*1)+(7*1)+(6*8)+(5*6)+(4*4)+(3*4)+(2*9)+(1*0)=139
139 % 10 = 9
So 118644-90-9 is a valid CAS Registry Number.
