Check Digit Verification of cas no
The CAS Registry Mumber 135773-40-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,5,7,7 and 3 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 135773-40:
(8*1)+(7*3)+(6*5)+(5*7)+(4*7)+(3*3)+(2*4)+(1*0)=139
139 % 10 = 9
So 135773-40-9 is a valid CAS Registry Number.
