93750-44-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 93750-44-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,3,7,5 and 0 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 93750-44:
(7*9)+(6*3)+(5*7)+(4*5)+(3*0)+(2*4)+(1*4)=148
148 % 10 = 8
So 93750-44-8 is a valid CAS Registry Number.
