91652-59-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 91652-59-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,1,6,5 and 2 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 91652-59:
(7*9)+(6*1)+(5*6)+(4*5)+(3*2)+(2*5)+(1*9)=144
144 % 10 = 4
So 91652-59-4 is a valid CAS Registry Number.
