Check Digit Verification of cas no
The CAS Registry Mumber 133414-90-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,3,4,1 and 4 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 133414-90:
(8*1)+(7*3)+(6*3)+(5*4)+(4*1)+(3*4)+(2*9)+(1*0)=101
101 % 10 = 1
So 133414-90-1 is a valid CAS Registry Number.
