103830-76-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 103830-76-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,3,8,3 and 0 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 103830-76:
(8*1)+(7*0)+(6*3)+(5*8)+(4*3)+(3*0)+(2*7)+(1*6)=98
98 % 10 = 8
So 103830-76-8 is a valid CAS Registry Number.
