380343-29-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 380343-29-3 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 3 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 380343-29:
(8*3)+(7*8)+(6*0)+(5*3)+(4*4)+(3*3)+(2*2)+(1*9)=133
133 % 10 = 3
So 380343-29-3 is a valid CAS Registry Number.
