87768-14-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 87768-14-7 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, 1 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 87768-14:
(7*8)+(6*7)+(5*7)+(4*6)+(3*8)+(2*1)+(1*4)=187
187 % 10 = 7
So 87768-14-7 is a valid CAS Registry Number.
