63156-74-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 63156-74-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,3,1,5 and 6 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 63156-74:
(7*6)+(6*3)+(5*1)+(4*5)+(3*6)+(2*7)+(1*4)=121
121 % 10 = 1
So 63156-74-1 is a valid CAS Registry Number.
