83238-59-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 83238-59-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,3,2,3 and 8 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 83238-59:
(7*8)+(6*3)+(5*2)+(4*3)+(3*8)+(2*5)+(1*9)=139
139 % 10 = 9
So 83238-59-9 is a valid CAS Registry Number.
