Check Digit Verification of cas no
The CAS Registry Mumber 135359-42-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,5,3,5 and 9 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 135359-42:
(8*1)+(7*3)+(6*5)+(5*3)+(4*5)+(3*9)+(2*4)+(1*2)=131
131 % 10 = 1
So 135359-42-1 is a valid CAS Registry Number.
