Check Digit Verification of cas no
The CAS Registry Mumber 90921-75-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,0,9,2 and 1 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 90921-75:
(7*9)+(6*0)+(5*9)+(4*2)+(3*1)+(2*7)+(1*5)=138
138 % 10 = 8
So 90921-75-8 is a valid CAS Registry Number.
