77133-98-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 77133-98-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,7,1,3 and 3 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 77133-98:
(7*7)+(6*7)+(5*1)+(4*3)+(3*3)+(2*9)+(1*8)=143
143 % 10 = 3
So 77133-98-3 is a valid CAS Registry Number.
