Check Digit Verification of cas no
The CAS Registry Mumber 90013-44-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,0,0,1 and 3 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 90013-44:
(7*9)+(6*0)+(5*0)+(4*1)+(3*3)+(2*4)+(1*4)=88
88 % 10 = 8
So 90013-44-8 is a valid CAS Registry Number.
