1373882-50-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1373882-50-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,7,3,8,8 and 2 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1373882-50:
(9*1)+(8*3)+(7*7)+(6*3)+(5*8)+(4*8)+(3*2)+(2*5)+(1*0)=188
188 % 10 = 8
So 1373882-50-8 is a valid CAS Registry Number.
