87768-83-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 87768-83-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,7,7,6 and 8 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 87768-83:
(7*8)+(6*7)+(5*7)+(4*6)+(3*8)+(2*8)+(1*3)=200
200 % 10 = 0
So 87768-83-0 is a valid CAS Registry Number.
