26957-77-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 26957-77-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,6,9,5 and 7 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 26957-77:
(7*2)+(6*6)+(5*9)+(4*5)+(3*7)+(2*7)+(1*7)=157
157 % 10 = 7
So 26957-77-7 is a valid CAS Registry Number.
