750638-22-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 750638-22-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 7,5,0,6,3 and 8 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 750638-22:
(8*7)+(7*5)+(6*0)+(5*6)+(4*3)+(3*8)+(2*2)+(1*2)=163
163 % 10 = 3
So 750638-22-3 is a valid CAS Registry Number.
