77540-97-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 77540-97-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,7,5,4 and 0 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 77540-97:
(7*7)+(6*7)+(5*5)+(4*4)+(3*0)+(2*9)+(1*7)=157
157 % 10 = 7
So 77540-97-7 is a valid CAS Registry Number.
