90708-59-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 90708-59-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,0,7,0 and 8 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 90708-59:
(7*9)+(6*0)+(5*7)+(4*0)+(3*8)+(2*5)+(1*9)=141
141 % 10 = 1
So 90708-59-1 is a valid CAS Registry Number.
