42976-08-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 42976-08-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,2,9,7 and 6 respectively; the second part has 2 digits, 0 and 8 respectively.Calculate Digit Verification of CAS Registry Number 42976-08:
(7*4)+(6*2)+(5*9)+(4*7)+(3*6)+(2*0)+(1*8)=139
139 % 10 = 9
So 42976-08-9 is a valid CAS Registry Number.
