16841-55-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 16841-55-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,6,8,4 and 1 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 16841-55:
(7*1)+(6*6)+(5*8)+(4*4)+(3*1)+(2*5)+(1*5)=117
117 % 10 = 7
So 16841-55-7 is a valid CAS Registry Number.
