Check Digit Verification of cas no
The CAS Registry Mumber 67756-38-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,7,7,5 and 6 respectively; the second part has 2 digits, 3 and 8 respectively.Calculate Digit Verification of CAS Registry Number 67756-38:
(7*6)+(6*7)+(5*7)+(4*5)+(3*6)+(2*3)+(1*8)=171
171 % 10 = 1
So 67756-38-1 is a valid CAS Registry Number.
