778557-15-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 778557-15-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 7,7,8,5,5 and 7 respectively; the second part has 2 digits, 1 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 778557-15:
(8*7)+(7*7)+(6*8)+(5*5)+(4*5)+(3*7)+(2*1)+(1*5)=226
226 % 10 = 6
So 778557-15-6 is a valid CAS Registry Number.
