76431-35-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 76431-35-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,6,4,3 and 1 respectively; the second part has 2 digits, 3 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 76431-35:
(7*7)+(6*6)+(5*4)+(4*3)+(3*1)+(2*3)+(1*5)=131
131 % 10 = 1
So 76431-35-1 is a valid CAS Registry Number.
