Check Digit Verification of cas no
The CAS Registry Mumber 12507-77-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,2,5,0 and 7 respectively; the second part has 2 digits, 7 and 7 respectively.Calculate Digit Verification of CAS Registry Number 12507-77:
(7*1)+(6*2)+(5*5)+(4*0)+(3*7)+(2*7)+(1*7)=86
86 % 10 = 6
So 12507-77-6 is a valid CAS Registry Number.
