1628798-91-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1628798-91-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,2,8,7,9 and 8 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1628798-91:
(9*1)+(8*6)+(7*2)+(6*8)+(5*7)+(4*9)+(3*8)+(2*9)+(1*1)=233
233 % 10 = 3
So 1628798-91-3 is a valid CAS Registry Number.
