380342-95-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 380342-95-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,8,0,3,4 and 2 respectively; the second part has 2 digits, 9 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 380342-95:
(8*3)+(7*8)+(6*0)+(5*3)+(4*4)+(3*2)+(2*9)+(1*5)=140
140 % 10 = 0
So 380342-95-0 is a valid CAS Registry Number.
