1835-76-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1835-76-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,8,3 and 5 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1835-76:
(6*1)+(5*8)+(4*3)+(3*5)+(2*7)+(1*6)=93
93 % 10 = 3
So 1835-76-3 is a valid CAS Registry Number.
