676487-33-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 676487-33-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,7,6,4,8 and 7 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 676487-33:
(8*6)+(7*7)+(6*6)+(5*4)+(4*8)+(3*7)+(2*3)+(1*3)=215
215 % 10 = 5
So 676487-33-5 is a valid CAS Registry Number.
