The CAS Registry Mumber 61836-37-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,1,8,3 and 6 respectively; the second part has 2 digits, 3 and 7 respectively. Calculate Digit Verification of CAS Registry Number 61836-37: (7*6)+(6*1)+(5*8)+(4*3)+(3*6)+(2*3)+(1*7)=131 131 % 10 = 1 So 61836-37-1 is a valid CAS Registry Number.
