76507-90-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 76507-90-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,6,5,0 and 7 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 76507-90:
(7*7)+(6*6)+(5*5)+(4*0)+(3*7)+(2*9)+(1*0)=149
149 % 10 = 9
So 76507-90-9 is a valid CAS Registry Number.
