37859-38-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 37859-38-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,7,8,5 and 9 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 37859-38:
(7*3)+(6*7)+(5*8)+(4*5)+(3*9)+(2*3)+(1*8)=164
164 % 10 = 4
So 37859-38-4 is a valid CAS Registry Number.
