103721-68-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 103721-68-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,3,7,2 and 1 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 103721-68:
(8*1)+(7*0)+(6*3)+(5*7)+(4*2)+(3*1)+(2*6)+(1*8)=92
92 % 10 = 2
So 103721-68-2 is a valid CAS Registry Number.
