The CAS Registry Mumber 4371-22-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,3,7 and 1 respectively; the second part has 2 digits, 2 and 2 respectively. Calculate Digit Verification of CAS Registry Number 4371-22: (6*4)+(5*3)+(4*7)+(3*1)+(2*2)+(1*2)=76 76 % 10 = 6 So 4371-22-6 is a valid CAS Registry Number.
