Check Digit Verification of cas no
The CAS Registry Mumber 90145-29-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,0,1,4 and 5 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 90145-29:
(7*9)+(6*0)+(5*1)+(4*4)+(3*5)+(2*2)+(1*9)=112
112 % 10 = 2
So 90145-29-2 is a valid CAS Registry Number.
