Check Digit Verification of cas no
The CAS Registry Mumber 131372-77-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,1,3,7 and 2 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 131372-77:
(8*1)+(7*3)+(6*1)+(5*3)+(4*7)+(3*2)+(2*7)+(1*7)=105
105 % 10 = 5
So 131372-77-5 is a valid CAS Registry Number.
