78857-91-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 78857-91-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,8,8,5 and 7 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 78857-91:
(7*7)+(6*8)+(5*8)+(4*5)+(3*7)+(2*9)+(1*1)=197
197 % 10 = 7
So 78857-91-7 is a valid CAS Registry Number.
